5 GENERAL TECHNICAL DATA

6 APPLICATION DATA INTRODUCTION The Purpose of instrument transformers: The purpose of instrument transformers is to reduce the voltage and current of an electrical network to standardized, non-hazardous levels. They isolate operators and instruments from the high voltage circuits allowing a less hazardous work environment. Without these transformers, measurements would require expensive insulated instrument panels. There are two types of instrument transformer: transformers (CT: Under normal operating conditions their secondary current is practically proportional to the primary current, and its phase is shifted by an angle close to zero. transformers (VT: Under normal operating conditions the secondary voltage is practically proportional to the primary voltage and its phase is shifted by an angle close to zero. CT A R VT W Figure 1: CT and VT diagram connection R VT VT VOLTAGE DESIGNATIONS Single-phase transformers (UR/UC/UX The U in the type name and the GY in the primary voltage column of the data sheet indicate that the VT has one fully insulated bushing, making it suitable for line-toground connection only /69000GY. This unit is rated for operating Volts. It can be connected at Volts line-to-ground on a Volt system (line-to-line Volts are V /34500GY. This unit is rated for operating Volts. However, it can only be connected line-to-ground on a V system. Therefore, the actual operating voltage of the unit would be 34500/ 3. The accuracy and thermal ratings of this unit are based on V. This is typical where there is a relay connected to the unit which should operate when there is a single lineto-ground fault. In this condition, the line-to-ground voltage becomes equal to the line-to-line voltage. V V R Phase-to-phase transformers (VR/VC/VX The V in the type name and the Y in the primary voltage column of the data sheet indicate that the VT has two fully insulated bushings, making it suitable for line-toline connection /47804Y. This unit is rated for operating Volts. It can be connected at Volts line-toground on a Volt system (line-to-line Volts are V OR it can be connected line-to-line on a system with V line-to-line. This unit is not suitable for operation at Volts /46000Y. This unit is rated for operating Volts. It can be connected at Volts line-to-line. RATING FACTORS Rating factors given in this brochure are standard at 30 C Characteristics for different thermal loadings on request. STANDARDS All the instrument transformers listed in this guide comply with the following standards where applicable: IEEE C Standard Requirements for Instrument transformers. ANSI C American National Standard for Instrument transformers for Revenue Metering 10kV BIL through 350 kv BIL (0.6 kv NSV through 69 kv NSV. CAN/CSA-C Instrument Transformers. IEC Instrument Transformers. HOW TO SPECIFY INSTRUMENT TRANSFORMERS There are several parameters that must be specified when ordering or requesting for proposals or quotations. If the requirements needed fits exactly into the characteristics listed in the data sheets of each model, it is enough to mention the code. However, when non-standard equipment will be needed, the following parameters must be specified: Highest nominal voltage system Basic impulse level (BIL Type of service (outdoor/indoor Frequency Ratio Only for current transformers Continuous thermal current rating factor Short-time thermal current (ka/1s Class and burden Only for voltage transformers Rated continuous voltage Rated voltage factor (30sec Total thermal burden class and burden

7 ACCURACY STANDARDS CURRENT TRANSFORMERS (CT The accuracy class of a current transformer for measuring is given by a number (class rate representing the ratio error limit expressed as a percentage of the rated primary current when the transformer is running at its accuracy load. classes for current transformers are: 0.15S; 0.15; 0.15N; 0.3S; 0.3; 0.6 and 1.2. For class 0.3, 0.6, 0.15N and 1.2 the ratio correction factor must fall within the parallelograms for 100% and 10% respectively. For accuracy class 0.15, 0.15S and 0.3S the ratio correction factor must fall within the parallelograms for 100% and 5% respectively. The following example calculates the correction factor for a current transformer with the following characteristics: 0.3 accuracy class 100% rated current Ratio correction factor: Maximum allowable phase angle: minutes Transformer Correction Factor = RCF (β/2600 = (15.6/2600 = The ratio correction factor and phase angle for any point inside the 0.3 class parallelogram for 100% rated current will always produce a TCF between and VOLTAGE TRANSFORMERS (VT The accuracy class of a voltage transformer for measuring is given by a number (class rate representing the ratio error limit expressed as a percentage of the rated primary voltage when the transformer is running at its accuracy load. classes for voltage transformers are: 0.15; 0.3; 0.6 and 1.2.

8 ACCURACY STANDARDS HIGH ACCURACY EXTENDED RANGE CURRENT TRANSFORMERS Extended range current transformers are designed for modern power generation systems. They accurately measure a wider range of current without making physical changes in the primary or in the secondary connections of a current transformer. To ensure the best performance on nominal primary current readings from 1% to Rating factor (please, see charts below, these current transformers have been designed using magnetic materials that minimize excitation losses and a winding distribution that virtually eliminates stray losses. High accuracy extended range current transformers can increase utility revenue through improved metering. This occurs on systems with variable currents such as wind or solar power generation. In the past, current transformers were designed to accurately measure down to 10% of the current rating on the name plate of the transformer. However, the recent deployment of variable generation has created a need to accurately measure a new range of currents produced by these systems; especially below the rated current of the transformer. Historically, some energy usage revenue went unmeasured. Today Arteche s high accuracy extended range current transformers accurately measure these variable loads. Extended range current transformers answer Standard CT s problem by expanding the amperage load that can be accurately measured. The wider current range helps to reduce the number of different ratios, reducing the amount of inventory needed to respond to customer demands. Standard Class 0.3 means that from 100% of nominal current through the rating factor, accuracy is guaranteed to be ±0.3%, and from 10% of nominal current through 100% of nominal current accuracy is guaranteed to be ±0.6%. 0.6% 0.3% Rated 10% 100% 150% (or Rating Factor High Class 0.15 means that from 100% of nominal current through the rating factor, accuracy is guaranteed to be ±0.15%, and from 5% of nominal current through 100% of nominal current accuracy is guaranteed to be ±0.3%. 0.3% 0.15% Rated 5% 100% 150% (or Rating Factor Class 0.3S means that from 5% of nominal current through the rating factor, accuracy is guaranteed to be ±0.3%. 0.3% Rated 5% 100% 150% (or Rating Factor Class 0.15S means that from 5% of nominal current through the rating factor, accuracy is guaranteed to be ±0.15%. 0.15% Rated 5% 100% 150% (or Rating Factor High, Extended Range Class 0.15 means that from 1% of nominal current through the rating factor, accuracy is guaranteed to be ±0.15%. This goes beyond IEEE C57.13 requirements. 0.15% Rated 1% 5% 100% 150% (or Rating Factor

The rack is made of lightweight aluminium designed to mount on poles in an upright position. It includes two galvanized steel mounting bolts for attaching the metering unit to the pole, with pole diameters available from 8 to 14. Optional galvanized steel structures and/or other pole diameters are available upon request. MK series incorporate 3 combined transformers mounted vertically. Their core is encapsulated with Type B epoxy resin which provides excellent internal dielectric properties and mechanical strength. The external layer of Cycloaliphatic Epoxy Resin (CEP provides resistance to ultraviolet rays and the effects of tracking and erosion on the exterior of the transformer ensuring a long mechanical and electrical life. The transformer is maintenance free. OUTDOOR 60 Hertz The external layer can be manufactured with Hydrophobic Cycloaliphatic Epoxy Resin (HCEP which improves service life expectancy due to its improved tracking and erosion resistance. HCEP additionally increases the transformer s weatherability and offers better performance in heavily polluted environments. The core is built with high permeability grain oriented silicon steel laminations for low losses. The windings are copper wire with copper plate double isolation.
