50 .1 Transformers NEMA TP-1 Energy-Efficient Transformers Accessories Please refer to Section.7 Page V-T-191. Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour, 150% load for one hour and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding + Hot Spot = Temp. Class 40 C 55 C 10 C 105 C 40 C 80 C 30 C 150 C 5 C 135 C 0 C 180 C 40 C 115 C 30 C 185 C 40 C 150 C 30 C 0 C The design life of transformers having different insulation systems is the same the lower-temperature systems are designed for the same life as the higher-temperature systems. Enclosures Eaton s ventilated transformers, s DS-3 and DT-3, use a NEMA rated (drip-proof) enclosure as standard, and are rated NEMA 3R with the addition of weathershields. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Encapsulated units have copper leads or stabs brought out for connections. Ventilated transformers have leads brought out to terminals that are pre-drilled to accept Cu/Al lugs. Aluminum-wound transformers have aluminum terminals; copper-wound models have copper terminals. Lugs are not supplied with these transformers. Eaton recommends external cables be rated 90 C (sized at 75 C ampacity) for encapsulated designs and 75 C for ventilated designs. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an x or / between the voltage ratings, such as voltages of 10/40 or 40 x 480. If the series-multiple winding is designated by an x, the winding can be connected only for a series or parallel. With the / designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 10 x 40 winding can be connected for either 10 (parallel) or 40 (series), but a 10/40 winding can be connected for 10 (parallel), or 40 (series), or 40 with a 10 mid-point. For additional information, please refer to Section.7 Page V-T-191. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-0 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation Average Sound Levels NEMA ST-0 Average Sound Level, db Equivalent Winding Self-Cooled Ventilated (up to 1. kv) kva Range K-Factor 1, 4, 9 K-Factor 13, 0 will likely be higher (as much as 15 db greater) due to electrical connections and environmental conditions.

51 NEMA TP-1 Energy-Efficient Transformers.1 K-Factor Product Description A common industry term for the amount of harmonics produced by a given load is the K-factor. The larger the K-factor, the more harmonics are present. Linear loads, for example, have a K-factor of 1. Transformers may carry a K-factor rating to define the transformer s ability to withstand the additional heating generated by harmonic currents. Calculating the K-Factor All nonlinear waveforms can be broken down mathematically into a fundamental frequency and its harmonics. IEEE C establishes a direct relationship between these harmonics and transformer heating. Underwriters Laboratories has established a similar relationship, the K-factor, which is derived by summing the square of the percentage current at a given harmonic level multiplied by the square of the harmonic order. K = ²( I h) (h) Ih = Percent Current at Harmonic h h = Harmonic Order, i.e., 3rd, 5th, 7th For example, a load that is 90% of the fundamental, 30% of the third harmonic, and 0% of the fifth harmonic would yield (.9) (1) + (.3) (3) + (.) (5) or a K-factor of.6. This load would require an Eaton KT-4 transformer with a K-factor rating of 4. Transformers that carry a K-factor rating define the transformer s ability to withstand a given harmonic load while operating within the transformer s insulation class. An analysis of harmonic loads and a calculation of the K-factor must be made to properly apply transformers in any building or facility. Note that the calculated K-factor is not constant because nonlinear loads change throughout the day as equipment and lighting is turned off and on. These harmonic loads also change over the life of the building or facility as equipment is added or removed. Harmonic Currents Harmonic currents are found in nonlinear loads. These currents are generated by various types of equipment including switching mode power supplies that abruptly switch current on and off during each line cycle. Switching mode power supplies or diode-capacitor power supplies convert AC line voltage to low voltage DC. This process is accomplished by charging capacitors during each line cycle with narrow pluses of current that are timecoincident with line voltage peaks. Examples of this equipment include electronic ballasts for fluorescent lighting, personal computers, printers, fax machines, electronic and medical test equipment, uninterruptible power supplies, and solid-state motor drives. Note: Nonlinear is synonymous with the term non-sinusoidal. Features, Benefits and Functions 600 volt class standard Three-phase, 480 delta 08Y/10 volt standard Single-phase, 40 x 480 volt 10/40 volt standard 150 C rise standard, 80 C and 115ºC available Three-phase neutrals sized for 00% of rated current Electrostatic shield Note: Electrostatic shields do not reduce harmonic levels. However, because of the nature of switching mode loads, these shields do reduce transient noise in the system, which may affect sensitive computer loads. Aluminum windings (copper optional) Class 0 C insulation Reduced core flux density Note: Reduced core flux prevents the core from saturation and overheating due to voltage distortions caused by harmonic currents.

60 .1 Transformers NEMA TP-1 Energy-Efficient Transformers Accessories Please refer to Section.7 Page V-T-191. Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour, 150% load for one hour, and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding + Hot Spot = Temp. Class 40 C 55 C 10 C 105 C 40 C 80 C 30 C 150 C 5 C 135 C 0 C 180 C 40 C 115 C 30 C 185 C 40 C 150 C 30 C 0 C The design life of transformers having different insulation systems is the same the lower-temperature systems are designed for the same life as the higher-temperature systems. Enclosures Eaton ventilated transformers, KT, use a NEMA rated (drip-proof) enclosure as standard, and are rated NEMA 3R with the addition of weathershields. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Ventilated transformers have leads brought out to aluminum pads that are predrilled to accept Cu/Al lugs. Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 75 C for ventilated designs. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-0 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and Average Sound Levels NEMA ST-0 Average Sound Level, db Equivalent Winding Self-Cooled Ventilated (up to 1. kv) kva Range K-Factor 1, 4, 9 K-Factor 13, 0 environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern.

For other ratings or catalog numbers not shown, or for special enclosure types (including stainless steel), refer to Eaton. The electrical transformer has been a staple of electrical power systems for the past 100+ years. While the types of electrical loads that are being added to our systems today have radically changed, the transformer has stayed relatively the same in design during this time frame. Eaton s harmonic mitigating transformer (HMT) represents the evolution of the transformer into something that will best provide clean, energyefficient electricity to power the loads of today and tomorrow. The recent shift of our electrical loads from predominately AC consumers (resistive heating elements, incandescent lighting, three-phase motor load) to DC consumers (such as computers, fax machines, printers, down to the wall-wart that recharges the cell phone) requires that our electrical infrastructure changes as well. These new loads now introduce other currents and frequencies into our electrical power systems commonly known as harmonics. Harmonic currents can cause additional heating, which may cause transformers, generators and conductors to become overloaded. Excessive heat is one of the major reasons that standard transformers and conductors fail prematurely. These harmonic currents have various other effects (such as loss of ride-through capability, reduced lifespan and mysterious misoperation of equipment) on the components and loads of an electrical distribution system. Eaton s HMTs, when used properly within an electrical system, will help keep the loads operating the way the manufacturer designed them and keep the facility s electrical system free from voltage distortion. Three-Phase, DT-3 HMT, 60 Hz Harmonic mitigating (cancellation) transformers are a cost-effective means of treating harmful harmonics in an electrical distribution system Reducing harmonic content in electrical systems can result in a more reliable electrical system, lower maintenance costs, less downtime, fewer equipment malfunctions, and lower cooling system capacity Available in a variety of phase-shift configurations that allow flexibility to target specific families of harmonics Harmonic treatment via electromagnetic flux cancellation May be installed as a stand-alone transformer, or included in IFS Available in three-phase ratings, kva, up to 600 volts primary Features and Benefits 480 volt to 08/10 volt standard.

89 Energy-Efficient Harmonic Mitigating Transformers.3 Accessories Harmonic mitigating transformers are available with the same options and accessories as generalpurpose ventilated transformers. Please refer to Section.7 Page V-T-191. Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capacity Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour; 150% load for one hour and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding + Hot Spot = Temp.

90 .3 Transformers Energy-Efficient Harmonic Mitigating Transformers Demystifying Harmonic Mitigating Transformer Myths Aren t power factor corrected computer power supplies fixing all harmonics? The use of power factor corrected computer power supplies is a great first start to reducing harmonic currents in your facility. These are becoming prevalent in server applications, but have not crossed-over into the laptop computer/business computer. Remember also that, once the computer power supply harmonics are addressed, you will still need to address the harmonic currents coming from the variety of other equipment in your facility. Don t K-rated transformers fix harmonics? The K-rated transformer was created to address the additional heat being produced by standard deltawye transformers when feeding nonlinear loads. The goal of the K-rated transformer is to dissipate the heat produced over a larger area, thus providing the illusion of correction. The K-rated transformer does nothing to reduce the root issue of harmonic currents or correct power quality issues. Because of their larger size, they also consume additional energy to do the same work and are counter-productive to an energy-efficient electrical distribution design. Don t you need two HMTs for any correction to occur? The design of HMTs allows them to address different families of harmonic currents in different ways. A single HMT will treat the triplen (3rd, 9th, 15th and so on) harmonic currents in its secondary winding. The 5th, 7th, 17th and 19th harmonic family is treated on a system basis through a technique known as phase shifting. This phase shift does occur between the NON and THR, and the POS and NEG harmonic mitigating transformers and this can also occur between a NON and a standard delta-wye transformer (that is probably already existing within your facility). See our Sample HMT Applications area for additional information. The cost of HMTs is too high! While the initial cost of HMTs is typically 1.5 to 4 times the cost of a standard transformer (due to the additional design, materials and labor involved in creating the magnetics necessary to reduce harmonic impact) to not use an HMT in a harmonic environment will actually cost you 50% more energy loss in the transformer. Due to the relatively long life of a transformer (0 30 years), these additional energy costs easily overshadow the initial one-time first cost increment. If I use one HMT, don t I need to change all my transformers? Most facilities have only a percentage (typically 0 5%) of their electrical system that really requires the use of an HMT. This means in a typical building that only a few areas are either critical (meaning high requirements for clean power) or have high concentrations of electronic, nonlinear loads requiring the use of the HMT in those specific areas. The harmonic mitigating transformer is a weapon in your arsenal in providing a complete, properly designed electrical system for today and tomorrow. Transformer Technology Table Explanation In understanding the product computer loads. (This is due placement of the HMT, it to the fact that the HMT becomes useful to have has a different design some rule of thumb than a standard delta-wye understanding to compare transformer and addresses products. Looking at one of the root issue of harmonic the aspects of an HMT currents.) A good analogy is price you can see that, to look at the incandescent if a standard delta-wye light bulb versus a compact transformer had a cost of fluorescent lamp you might one unit, a K-13 transformer pay a bit more up front, but would cost about double and because of the large energy an HMT would cost 1.5 to savings (because of the 4 times the unit cost.

It s very typical to head-on! Referring to the return the price differential table s information, you can between the HMT and a see that it would take 30% standard transformer with a more energy to power the few years thus using the same computer loads with additional 0 to 30 years of a K-13 transformer, whereas energy savings to add to your an HMT would take 5% less bottom line. energy to feed those same Transformer Technology Comparison 1 Transformer Cost Energy Savings Power Quality Standard delta-wye if 1X if 1X Not designed for harmonics K X 0.3X Bulked up doesn t help HMT.5X.5X Corrects root issue Note 1 Comparing cost, energy savings and power quality performance between the commonly used transformer types.

91 Energy-Efficient Harmonic Mitigating Transformers.3 Sample HMT Applications Typical Application of NON Transformer NON Long Run Electrical Bus Installation of a NON transformer provides an effective treatment of triplen (3rd, 9th, 15th and so on) harmonic currents that are generated by loads connected to the transformer. Triplen harmonic currents are treated in the secondary windings of the transformer due to the transformer s low zero sequence impedance. NON transformers do not need to be used in combination with other transformers to treat triplen harmonic currents. A single NON transformer may be installed, or multiple units can be applied. Electrical Panel Feeding Single-Phase and/or Three-Phase Nonlinear Loads NON NON transformers are an ideal solution for treating triplen harmonics generated by personal computers, printers, fax machines and other office equipment, as well as by single-phase electronic ballasts, and singlephase electronic testing or monitoring devices. Typical Application of NON Transformer with a Standard Delta-Wye Transformer NON -Y Transformer Long Run Electrical Bus When a delta-wye transformer exists in an electrical distribution system, the addition of a NON transformer offers an economical solution for treating harmonic currents. The 30 phase-shift created between a NON harmonic mitigating transformer and a delta-wye transformer (standard transformer or K-Factor transformer) provides treatment of 5th, 7th, 17th and 19th harmonic currents. These harmonic currents are canceled in the common electrical bus that feeds the transformers. Additionally, Electrical Panel Feeding Single-Phase and/or Three-Phase Nonlinear Loads NON -Y Transformer triplen (3rd, 9th, 15th and so on) harmonic currents generated by the loads connected to the NON transformer will be treated in the secondary windings of the NON transformer due to its low zero sequence impedance. When using two or more transformers to treat harmonics, it is better that the load be split equally between the transformers to receive the maximum benefit. Note: Triplen currents will still circulate in the delta-wye transformer for additional waste. See figure on Page V-T-9 to correct. Volume Commercial Distribution CA E July V-T-91

92 .3 Transformers Energy-Efficient Harmonic Mitigating Transformers Optimum Application of NON and THR Transformers NON THR Long Run Electrical Bus When you re searching for an optimum harmonic correction solution in an electrical distribution system, the combination of a NON and THR transformer offers a great solution. The 30 phase shift created between NON and type THR harmonic mitigating transformers provides treatment of 5th, 7th, 17th and 19th harmonic currents. These harmonic currents are canceled in the common electrical bus that feeds the transformers. Additionally, Electrical Panel Feeding Single-Phase and/or Three-Phase Nonlinear Loads NON THR triplen (3rd, 9th, 15th and so on) harmonic currents generated by the loads will be treated in the secondary windings of HMTs. This will ensure that these currents will not circulate in the primary of the transformer creating additional heat, voltage distortion and wasted energy loss. When using two or more transformers to treat harmonics, it is better that the load be split equally between the transformers to receive the maximum benefit. Typical Application of NEG and POS Transformers NEG POS Long Run Electrical Bus The combination of a POS (+15 phase-shift) transformer and a NEG ( 15 phase-shift) transformer effectively treats 5th, 7th, 17th and 19th harmonic currents. These harmonic currents are canceled in the common electrical bus that feeds the transformers. Additionally, triplen (3rd, 9th, 15th and so on) harmonic Electrical Panel Feeding Single-Phase and/or Three-Phase Nonlinear Loads NEG POS currents generated by the loads connected to these transformers will be treated in their secondary windings due to their low zero sequence impedance. When using two or more transformers to treat harmonics, it is better that the load be split equally between the transformers to receive the maximum benefit.

109 General-Purpose Encapsulated Transformers.4 Accessories Please refer to Section.7 Page V-T-191. Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour, 150% load for one hour and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding + Hot Spot = Temp. Class 40 C 55 C 10 C 105 C 40 C 80 C 30 C 150 C 5 C 135 C 0 C 180 C 40 C 115 C 30 C 185 C 40 C 150 C 30 C 0 C The design life of transformers having different insulation systems is the same the lower-temperature systems are designed for the same life as the higher-temperature systems. Enclosures Eaton encapsulated transformers, s EP and EPT, use a NEMA 3R rated enclosure as standard. NEMA 4X enclosures (grade 304 or 316 stainless steel) are available as an option. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Encapsulated units have copper leads or stabs brought out for connections. Ventilated transformers have leads brought out to aluminum pads that are predrilled to accept Cu/Al lugs. Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 90 C (sized at 75 C ampacity) for encapsulated designs and 75 C for ventilated designs. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an x or / between the voltage ratings, such as voltages of 10/40 or 40 x 480. If the series-multiple winding is designated by an x, the winding can be connected only for a series or parallel. With the / designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 10 x 40 winding can be connected for either 10 (parallel) or 40 (series), but a 10/40 winding can be connected for 10 (parallel), 40 (series) or 40 with a 10 mid-point. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-0 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to Average Sound Levels NEMA ST-0 Average Sound Level, db Equivalent Winding Self-Cooled Ventilated (up to 1. kv) kva Range K-Factor 1, 4, 9 K-Factor 13, 0 electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern.

118 .5 Transformers Distribution Transformers Accessories Copper windings Non-standard voltages 50/60 Hz designs Delta-delta configuration 80 C or 115 C rise designs Encapsulated designs (up to 34 kva). Thermoguards are not available on encapsulated designs Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour, 150% load for one hour and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Totally enclosed non-ventilated Electrostatic shields Please refer to Section.7 Page V-T-191. Insulation System and Temperature Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding + Hot Spot = Temp.

Enclosures Eaton ventilated transformers, MD, use a NEMA rated (drip-proof) enclosure as standard, and are rated NEMA 3R with the addition of weathershields. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Ventilated transformers have leads brought out to aluminum pads that are predrilled to accept Cu/Al lugs. Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 75 C for ventilated designs. Average Sound Levels NEMA ST-0 Average Sound Level, db Equivalent Winding Self-Cooled Ventilated (up to 1. kv) kva Range K-Factor 1, 4, 9 K-Factor 13, 0 Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-0 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern.

123 Distribution Transformers.5 Accessories Please refer to Section.7 Page V-T-191. Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour, 150% load for one hour and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding + Hot Spot = Temp. Class 40 C 55 C 10 C 105 C 40 C 80 C 30 C 150 C 5 C 135 C 0 C 180 C 40 C 115 C 30 C 185 C 40 C 150 C 30 C 0 C The design life of transformers having different insulation systems is the same the lower-temperature systems are designed for the same life as the higher-temperature systems. Winding Terminations Eaton recommends that external cables be rated 90 C (sized at 75 C ampacity) for encapsulated designs and 75 C for ventilated designs. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-0 sound levels listed here.

For other ratings or catalog numbers not shown, or for special enclosure types (including stainless steel), refer to Eaton. Suitable for indoor or outdoor applications Totally enclosed, nonventilated enclosures rated NEMA 3R 0 C insulation system 150 C rise standard; 115 C or 80 C rise optional Application Description Totally enclosed nonventilated dry-type transformers are for special applications, where because of adverse atmospheric conditions it is desirable to use a dry-type non-ventilated transformer vs. the ventilated standard unit, which has openings in its enclosure to allow air to flow directly over the core and coil. In applications where the atmosphere contains conductive, corrosive, or combustible materials, which might damage a transformer, or lint and dust flyings that might block the ventilation passages, the non-ventilated transformer is highly suited. It has no openings in the enclosure. Heat is dissipated by radiating from the surface area of the enclosure. Consequently, the enclosures are larger than those of the standard ventilated type. Non-ventilated transformers are suited for application in the textile, chemical, automotive, petrochemical, foundry, cement, food, paper and other industries.

Enclosures Eaton totally enclosed, non-ventilated transformers, s DS-3E and DT-3E, use a NEMA 3R rated enclosure as standard. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Totally enclosed nonventilated transformers have leads brought out to aluminum pads that are pre-drilled to accept Cu/Al lugs. Lugs are not supplied with these transformers. Eaton recommends external cables be rated 75 C for ventilated designs. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an x or / between the voltage ratings, such as voltages of 10/40 or 40 x 480. If the series-multiple winding is designated by an x, the winding can be connected only for a series or parallel. With the / designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 10 x 40 winding can be connected for either 10 (parallel) or 40 (series), but a 10/40 winding can be connected for 10 (parallel), or 40 (series), or 40 with a 10 mid-point.

132 .5 Transformers Distribution Transformers Accessories Please refer to Section.7 Page V-T-191. Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour, 150% load for one hour, and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding + Hot Spot = Temp. Class 40 C 55 C 10 C 105 C 40 C 80 C 30 C 150 C 5 C 135 C 0 C 180 C 40 C 115 C 30 C 185 C 40 C 150 C 30 C 0 C The design life of transformers having different insulation systems is the same the lower-temperature systems are designed for the same life as the higher-temperature systems. Winding Terminations Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 90 C (sized at 75 C ampacity) for encapsulated designs and 75 C for ventilated designs. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an x or / between the voltage ratings, such as voltages of 10/40 or 40 x 480. If the seriesmultiple winding is designated by an x, the winding can be connected only for a series or parallel. With the / designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 10 x 40 winding can be connected for either 10 (parallel) or 40 (series), but a 10/40 winding can be connected for 10 (parallel), 40 (series) or 40 with a 10 mid-point.

These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern.

143 Distribution Transformers.5 Accessories Please refer to Section.7 Page V-T-191. Technical Data and Specifications Frequency Eaton standard dry-type distribution transformers are designed for 60 Hz operation. Transformers required for other frequencies are available and must be specifically designed. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour, 150% load for one hour, and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding + Hot Spot = Temp. Class 40 C 55 C 10 C 105 C 40 C 80 C 30 C 150 C 5 C 135 C 0 C 180 C 40 C 115 C 30 C 185 C 40 C 150 C 30 C 0 C The design life of transformers having different insulation systems is the same the lower-temperature systems are designed for the same life as the higher-temperature systems. Enclosures Eaton ventilated transformers s DS-3M and DT-3M use a NEMA rated (drip-proof) enclosure as standard, and are rated NEMA 3R with the addition of weathershields. Eaton encapsulated transformers s EPM and EPTM use a NEMA 3R rated enclosure. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Encapsulated units have copper leads or stabs brought out for connections. Ventilated transformers have leads brought out to aluminum pads that are predrilled to accept Cu/Al lugs. Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 90 C (sized at 75 C ampacity) for encapsulated designs and 75 C for ventilated designs. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an x or / between the voltage ratings, such as voltages of 10/40 or 40 x 480. If the seriesmultiple winding is designated by an x, the winding can be connected only for a series or parallel. With the / designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 10 x 40 winding can be connected for either 10 (parallel) or 40 (series), but a 10/40 winding can be connected for 10 (parallel), 40 (series) or 40 with a 10 mid-point. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-0 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and Average Sound Levels NEMA ST-0 Average Sound Level, db Equivalent Winding Self-Cooled Ventilated (up to 1. kv) kva Range K-Factor 1, 4, 9 K-Factor 13, 0 environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern.

145 Distribution Transformers.5 Product Selection For quick selection data, refer to the tables on this and the following pages. Selection Requirements You should have the following information before selecting a buck-boost transformer: Line Voltage The voltage that you want to buck (decrease) or boost (increase). This can be found by measuring the supply line voltage with a voltmeter. Load Voltage The voltage at which your equipment is designed to operate. This is listed on the nameplate of the load equipment. Load Amperes or Load kva You do not need to know both one or the other is sufficient for selection purposes. This information usually can be found on the nameplate of the equipment that you want to operate. Frequency The supply line frequency must be the same as the frequency of the equipment to be operated Eaton s buck-boost transformers operate at 60 Hz only. Phase The supply line should be the same as the equipment to be operated either singleor three-phase. Transformer Interconnection For three-phase applications, interconnections of transformers should be made in a junction box. Two or three transformers may be used depending on an open delta () or wye (3) connection. 5-Step Selector The tables that follow will simplify the selection of the buck-boost transformers. There are no calculations needed; simply follow these five steps: 1. Refer to the table having the same output voltage as the equipment you want to operate. For example, if you are installing a 40 volt 6 kva single-phase load use selection table on the page.. Select the available line voltage across the top of the chart that is closest to the actual supply voltage. Therefore, for example, if the available line voltage is 13 volts, use the 1 volt column. 3. Read down the column until you reach an output kva or amps rating equal to or greater than the load requirements. Since 6 kva, in the example, is not listed, use the next higher rating, or 7.5 kva. 4. Read across to the far left columns for the catalog number and quantity of transformers for your application. In this case, you will need one (1) catalog number S10N06P01P. 5. Connect the buck-boost transformer(s) you have selected in accordance with the connection diagram specified at the bottom of the available line voltage column. In this example, Diagram F would be used. Note: For single-phase connections and three-phase open delta connections, inputs and outputs may be reversed. kva capacity remains constant.

171 Distribution Transformers.5 Accessories Please refer to Section.7 Page V-T-191. Technical Data and Specifications Frequency Eaton buck-boost transformers are designed for 60 Hz operation. Overload Capability Short-term overload is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour, 150% load for one hour, and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Insulation System and Temperature Industry standards classify insulation systems and rise as shown below: Insulation System Classification Ambient + Winding + Hot Spot = Temp. Class 40 C 55 C 10 C 105 C 40 C 80 C 30 C 150 C 5 C 135 C 0 C 180 C 40 C 115 C 30 C 185 C 40 C 150 C 30 C 0 C The design life of transformers having different insulation systems is the same the lower-temperature systems are designed for the same life as the higher-temperature systems. Enclosures Eaton encapsulated buckboost transformers use a NEMA 3R rated enclosure. Winding Terminations Primary and secondary windings are terminated in the wiring compartment. Encapsulated units have copper leads or stabs brought out for connections. Lugs are not supplied with these transformers. Eaton recommends that external cables be rated 90 C (sized at 75 C ampacity) for encapsulated designs. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with an x or / between the voltage ratings, such as voltages of 10/40 or 40 x 480. If the series-multiple winding is designated by an x, the winding can be connected only for a series or parallel. With the / designation, a mid-point also becomes available in addition to the series or parallel connection. As an example, a 10 x 40 winding can be connected for either 10 (parallel) or 40 (series), but a 10/40 winding can be connected for 10 (parallel), 40 (series) or 40 with a 10 mid-point. Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-0 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern. For additional information, please refer to Section.7 Page V-T-195. Average Sound Levels Note: When installation is to be made on a grounded system, consideration must be given to the resulting voltage. Thus, on a 08 grounded wye/10 system, the voltage can be boosted to 40 volts but the voltage to ground will be 139 volts. If 40/10 volts with a mid-point ground is needed, a standard two-winding transformer must be used. The following formulas can be used to calculate specific requirements.

195 Transformer Standards, Technical Data and Accessories.6 Technical Data and Specifications Customer-Furnished Connecting Cables Eaton recommends that external cables be rated 90 C (sized at 75 C ampacity) for encapsulated designs and 75 C for ventilated designs. Primary and secondary terminal lugs are not included. Lug kits are available separately. Overload Capability Short-term overload capacity is designed into transformers as required by ANSI. Dry-type distribution transformers will deliver 00% nameplate load for one-half hour, 150% load for one hour and 15% load for four hours without being damaged, provided that a constant 50% load precedes and follows the overload. See ANSI C for additional limitations. Continuous overload capacity is not deliberately designed into a transformer because the design objective is to be within the allowed winding temperature rise with nameplate loading. Seismically Qualified Eaton manufactured dry-type distribution transformers are seismically qualified, and exceed requirements of the Uniform Building Code (UBC) and California Code Title 4. Taps Primary taps are available in most ratings to allow compensation for source voltage variations. Series-Multiple Windings Series-multiple windings consist of two similar coils in each winding that can be connected in series or parallel (multiple). Transformers with series-multiple windings are designated with a x or / between the voltage ratings, such as voltages of 10/40 or 40 x 480. If the series-multiple winding is designated by an x, the winding can be connected only for a series or parallel. With the / designation, a midpoint also becomes available in addition to the series or parallel connection. As an example, a 10 x 40 winding can be connected for either 10 (parallel) or 40 (series), but a 10/40 winding can be connected for 10 (parallel), 40 (series) or 40 with a 10 midpoint. Enclosures Eaton s ventilated transformers s DS-3, DT-3, MD and KT use a NEMA rated (drip-proof) enclosure as standard, and are rated NEMA 3R with the addition of weathershields. Eaton encapsulated s EP, EPT, EPZ and EPTZ and totally enclosed, nonventilated (s DS-3E and DT-3E) transformers use a NEMA 3R rated enclosure. Buck-Boost Transformers An autotransformer has only one winding, and is therefore smaller and more economical than the conventional twowinding transformer. In an autotransformer, the primary and secondary are electrically and mechanically connected. The required secondary voltage is obtained by tapping-off from the single winding. Buck-boost autotransformers are insulated units with 10 x 40 or 40 x 480 volt primaries and 1/4, 16/3 or 4/48 volt secondaries, and provide a very economical method for minor voltage adjustments where circuit isolation is not needed. Autotransformers can be used only where local electrical codes permit, and isolation of the two circuits is not required. Nonlinear Ratings The transformers shall be specifically designed to supply circuits with a harmonic profile equal to or less than a K-factor of 4 or 13, as described in the following table, without exceeding specified temperature rise. Nonlinear Ratings Harmonic K-4 K-13 Fundamental 100.0% 100.0% 3rd 34.0% 70.0% 5th.0% 4.0% 7th 3.0% 5.0% 9th 1.0% 3.0% 11th 0.7% 3.0% 13th 0.5% 1.0% 15th 0.3% 0.7% 17th 0.3% 0.6% Sound Levels All Eaton 600 volt class general-purpose dry-type distribution transformers are designed to meet NEMA ST-0 sound levels listed here. These are the sound levels measured in a soundproof environment. Actual sound levels measured at an installation will likely be higher (up to 15 db greater) due to electrical connections and environmental conditions. Lower sound levels are available and should be specified when the transformer is going to be installed in an area where sound may be a concern. All Eaton general-purpose dry-type distribution transformers are designed with sound levels lower than NEMA ST-0 maximum levels. However, consideration should be given to the specific location of the transformers and their installation to minimize the potential for sound transmission to surrounding structures and sound reflection. It is suggested that the following installation methods be included: 1. If possible, mount the transformer away from corners of walls or ceilings. For installation that must be near a corner, use soundabsorbing materials on the walls and ceilings if necessary to eliminate reflection.. Provide a solid foundation for mounting the transformer and then use vibration dampening mounts if not already provided in the transformer. (Eaton encapsulated EP/EPT designs use a special encapsulation system and ventilated DS/DT-3 designs contain a built-in vibration dampening system to minimize and isolate sound transmission.) 3. Provide flexible conduit to make the connections to the transformer. 4. Locate the transformer as far as possible from areas where high sound levels are undesirable.

212 .6 Transformers Transformer Standards, Technical Data and Accessories EPACT: The Energy Policy Act of 199 (EPAct) is an important piece of legislation for efficiency because it established minimum efficiency levels for dry-type distribution transformers manufactured or imported after December 006. EPAct, which was based on NEMA standards, defined a number of terms, including what constitutes an energyefficient transformer. The DOE issued a rule that defines these transformers and how manufacturers must comply. DOE EPAct rule (PDF): Energy Efficiency Program for Certain Commercial and Industrial Equipment: Test Procedures, Labeling, and the Certification Requirements for Electric Motors. Final Rule. 10-CFR Part 431. Excitation current: No load current. The current that flows in any winding used to excite the transformer when all other windings are open-circuited. It is usually expressed in percent of the rated current of a winding in which it is measured. Also called magnetizing current. FCAN: Full Capacity Above Nominal taps. Designates the transformer will deliver its rated kva when connected to a voltage source which is higher than the rated primary voltage. : Full Capacity Below Nominal taps. Designates the transformer will deliver its rated kva when connected to a voltage source which is lower than the rated primary voltage. Frequency: On AC circuits, designates the number of times that polarity alternates from positive to negative and back again per second, such as 60 cycles per second. Typically measured in Hertz (Hz). Ground: Connecting one side of a circuit to the earth through low resistance or low impedance paths to help prevent transmitting electrical shock to personnel. Harmonic: A sinusoidal waveform with a frequency that is an integral multiple of the fundamental frequency (60 Hz). 60 H 3 fundamental 10 H 3 nd harmonic 180 H 3 3rd harmonic 40 H 3 4th harmonic Harmonic distortion: Nonlinear distortion of a system characterized by the appearance of harmonic (non-sinusoidal) currents in the output, when the input is sinusoidal. Harmonic distortion, total (THD): The square root of the sum of the squares of all harmonic currents present in a load, excluding the fundamental 60 Hz current. Usually expressed as a percent of the fundamental. High voltage windings: In a two-winding transformer, the winding intended to have the greater voltage. Usually marked with H designations. HMT: Harmonic Mitigating Transformer (HMT) is better able to handle the harmonic currents present in today s electrical power system. thereby increasing system capacity, reducing distortion throughout a facility, help to minimize downtime and mysterious maintenance on equipment, and return the longevity of equipment life through reduced operational energy losses, thereby running cooler. Hp: Horsepower. The energy required to raise 33,000 pounds a distance of one foot in one minute. 1 hp is equal to 746 watts, or kw. Hi pot: A standard test on dry-type transformers consisting of extra-high potentials (voltages) connected to the windings. Used to check the integrity of insulation materials and clearances. Hottest-spot temperature: The highest temperature inside the transformer winding. Is greater than the measured average temperature of the coil conductors, when using the resistance change method.

214 .6 Transformers Transformer Standards, Technical Data and Accessories Frequently Asked Questions About Transformers Can 60 Hz transformers be used at other frequencies? Transformers rated for 60 Hz can be applied to circuits with a higher frequency, as long as the nameplate voltages are not exceeded. The higher the frequency that you apply to a 60 Hz transformer, the less voltage regulation you will have. 60 Hz transformers may be used at lower frequencies but only at reduced voltages corresponding to the reduction in frequency. For example, a 480 to 10 volt 60 Hz transformer can carry rated kva at 50 Hz but ONLY when applied as a 400 to 100 volt transformer (50/60 x 480 = 400). Can single-phase transformers be used on a three-phase source? Yes. Any single-phase transformer can be used on a three-phase source by connecting the primary terminals of the single-phase transformer to any two wires of a three-phase system. It does not matter whether the three-phase source is threephase three-wire or threephase four-wire. The output of the transformer will be single-phase. Can transformers be used to create three-phase power from a single-phase system? No. Single-phase transformers alone cannot be used to create the phaseshifts required for a threephase system. Phase shifting devices (reactors or capacitors) or phase converters in conjunction with transformers are required to change singlephase power to three-phase. What considerations need to be taken into account when operating transformers at high altitudes? At altitudes greater than 3300 feet (1000 meters), the density of the air is less than at lower elevations. This reduces the ability of the air surrounding a transformer to cool it, so the temperature rise of the transformer is increased. Therefore, when a transformer is being installed at altitudes greater than 3300 feet above sea level, it is necessary to derate the usable capacity of the transformer. The table below lists the derating factors. As an example, a 75 kva 480V 08Y/10V transformer installed at 10,000 feet needs to be derated by 4%. Instead of 08A output, the usable current is only 199A. Altitude Feet Meters Current Rating Factor , , , , What considerations need to be taken into account when operating transformers where the ambient temperature is high? Eaton s dry-type transformers are designed in accordance with ANSI standards to operate in areas where the average maximum ambient temperature is 40 C. For operation in ambient temperatures above 40 C, there are two options: 1. Order a custom designed transformer made for the specific application.. Derate the nameplate kva of a standard transformer by 8% for each 10 C of ambient above 40 C. What is the normal life expectancy of a transformer? When a transformer is operated under ANSI/IEEE basic loading conditions ANSI C57.96), its normal life expectancy is 0 years. The ANSI/IEEE basic loading conditions are: A. The transformer is continuously loaded at rated kva and rated voltages. B. The average temperature of the ambient air during any 4-hour period is equal to 30 C and at no time exceeds 40 C. C. The altitude where the transformer is installed does not exceed 3300 feet (1000 meters). What are insulation classes? Insulation classes were originally used to distinguish insulating materials operating at different temperatures. In the past, letters were used for the different designations. Recently, insulation system temperatures ( C) have replaced the letters designations. Insulation Classes Previous Designation Class A 105 Class B 150 Class F 180 Class H 0 Class R 0 Insulation System Rating ( C) How do you know if the enclosure temperature is too hot? UL and CSA standards strictly regulate the highest temperature that an enclosure can reach. For ventilated transformers, the temperature of the enclosure should not increase by more than 50 C in a 40 C ambient at full rated current. For encapsulated transformers, the temperature of the enclosure should not increase by more than 65 C in a 5 C ambient at full rated current. This means that it is permissible for the temperature of the enclosure to reach 90 C (194 F). Although this temperature is very warm to the touch, it is within the allowed standards. A thermometer should be used to measure enclosure temperatures, not your hand. Can transformers be reverseconnected (reverse-fed)? Yes, with limitations. Eaton single-phase transformers rated 3 kva and larger can be reverse-connected without any loss of kva capacity or any adverse effects. Transformers rated kva and below, because there is a turns ratio compensation on the low voltage winding that adjusts voltage between no load and full load conditions, should not be reverse-fed. Three-phase transformers with either delta-delta or delta-wye configurations can also be reverseconnected for step-up operation. When reversefeeding a delta-wye connected transformer, there are two important considerations to take into account: (1) The neutral is not connected, only the three-phase wires of the wye system are connected, and () the ground strap between X0 and the enclosure must be removed. Due to high inrush currents that may be created in these applications, it is recommended that you do not reverse-feed transformers rated more than 75 kva. The preferred solution is to purchase an Eaton step-up transformer designed specifically for your application. V-T-14 Volume Commercial Distribution CA E July 016

215 Transformer Standards, Technical Data and Accessories.6 Can transformers be connected in parallel? Yes, with certain restrictions. For single-phase transformers being connected in parallel, the voltages and impedances of the transformers must be equal (impedances must be within 7.5% of each other). For three-phase transformers, the same restrictions apply as for single-phase transformers, plus the phase shift of the transformers must be the same. For example, a deltawye connected transformer (30 phase shift) must be connected in parallel with another delta-wye connected transformer, not a delta-delta connected transformer (0 phase shift). Why is the impedance of a transformer important? The impedance of a transformer is important because it is used to determine the interrupting rating and trip rating of the circuit protection devices on the load or line side of the transformer. To calculate the maximum short circuit current on the load side of a transformer, use the following formula: Maximum Short Circuit = Load Current (Amps) Full Load Current (Amps) Transformer Impedance Full load current for singlephase circuits is: Nameplate Volt-Amps Load (output) Voltage and for three-phase circuits, the full load current is: Nameplate Volts-Amps Load (output) Volts 3 Example: For a standard three-phase, 75 kva transformer, rated 480 volt delta primary and 08Y/ 10 volt secondary (catalog number V48M8T75J) and impedance equal to 5.1%, the full load current is: ,000 VA = 08V A The maximum short circuit load current is: 08.A = 4, 08.4A The circuit breaker or fuse on the secondary side of this transformer would have to have a minimum interrupting capacity of 4083 amperes at 08 volts. NEMA ST-0 (199). A similar transformer with lower impedance would require a primary circuit breaker or fuse with a higher interrupting capacity. What clearances are required around transformers when they are installed? All dry-type transformers depend upon the circulation of air for cooling; therefore, it is important that the flow of air around a transformer not be impeded. UL 1561 requires that there be no less than 6 inches (15.4 mm) clearance between any side transformer with ventilation openings and any wall or obstruction. In compliance with NEC 450.9, Eaton s ventilated transformers have a note on their nameplates requiring a minimum of 6 inches (15.4 mm) clearance from the ventilation openings and walls or other obstructions. This clearance only addresses the ventilation needs of the transformer. There may be additional local codes and standards that affect installation clearances. Transformers should not be mounted in such a manner that one unit will contribute to the additional heating of another unit, beyond allowable temperature limits, for example, where two units are mounted on a wall one above the other.
