Outdoor Distribution ( kv through kv) Specifications Conditions of Sale STANDARD: Seller s standard conditions of sale set forth in Price Sheet 150 apply. SPECIAL TO THIS PRODUCT: INCLUSIONS: S&C Vista Underground Distribution Switchgear features load-interrupter switches for switching - or 900-ampere main feeders, and microprocessor controlled arc-spinners or vacuum fault interrupters for switching and protection of - or 900-ampere main feeders and 200-, -, or 900-ampere taps, laterals, and subloops. These elbow-connected components are enclosed in a SF 6 - insulated, welded-steel tank, completely protected from the environment. The switchgear is available with up to six ways (bus terminals, switches and/or fault interrupters) in ratings through kv and 25 ka symmetrical. The three-position (closed-open-grounded) loadinterrupter switches are manually operated and provide three-pole live switching of - or 900-ampere three-phase circuits. These switches also provide a visible gap when open and internal grounding for all three phases without exposure to medium voltage or the need to manipulate elbows. The 200-ampere, -ampere, or 900-ampere fault interrupters feature either arc-spinning contacts (-kv, 12,500-symmetrical models) or vacuum interrupters in series with manually operated three-position (closed-opengrounded) disconnects (-kv, 25,000-symmetrical, and all -kv and -kv models) for isolation and internal grounding of each phase. Fault interrupters provide three-pole load switching and fault interruption through 25 ka symmetrical, or singlepole load switching and fault interruption through 12.5 ka symmetrical (for other possible ratings, refer to the nearest S&C Sales Office). Fault interruption is initiated by a programmable overcurrent control. The total clearing time (from initiation of the fault to total clearing) can be as fast as 40 milliseconds. For single-pole fault interrupters, the overcurrent control can also be programmed to provide three-pole fault interruption. Large windows provide a clear view of the open gap, ground position, and ground bus... allowing the operator to easily confirm the positions of the load-interrupter switches and disconnects of the fault interrupters. Trip indicators, which are readily visible through the windows, are provided for the fault interrupters. Each unit of gear is furnished with a manual handle to charge the operating mechanisms and open, close, and ground the load-interrupter switches and fault interrupters. The operating mechanisms operate independently of the speed of the manual handle and are designed to prevent inadvertent operation from the closed position directly to the ground position and vice versa. Operating shafts are padlockable in any position and can also be padlocked to prevent operation to the ground position. Terminals are equipped with 200-ampere-rated bushing wells or - or 900-ampere bushings (as specified). Bushing and bushing-well interfaces are in accordance with IEEE Standard 6 to accept all standard insulated connectors and inserts. In addition, Vista UDS has been certified as arc resistant per IEC 8 Appendix AA for fault currents up to 12.5 ka symmetrical for 15 cycles (25 ka symmetrical for units rated 25 ka short circuit). Arc resistance is standard for the Pad- Mounted and UnderCover Styles. For the Vault-Mounted Styles, Catalog Number Suffix -N must be specified, in which case a flange will be welded to the pressure relief device for connection of user-supplied piping to vent exhaust gases out of the vault area. When optional voltage indication is specified, all routine operating tasks switching, voltage testing, and grounding can be accomplished by a single person without cable handling or exposure to medium voltage. An optional feature that combines voltage indication with provisions for low-voltage phasing is also available. Cable testing for faults can be performed through the back of a user-supplied elbow or through a user-supplied feed thru insert eliminating the need for difficult cable handling or parking stands. The programmable overcurrent control is programmed using a personal computer connected to the control through an adapter cable (listed in the table of ACCESSORIES on page 11). Power and input signals are provided by current transformers. The control features a variety of time-current characteristic (TCC) curves standard E and K speed curves, innovative coordinating speed tap and main curves, and relay curves per IEEE C37.112-1996. Coordinating-speed tap curves are used for fault interrupters feeding subloop taps and are specifically designed to optimize coordination with load-side weak link/backup current-limiting fuse combinations and source-side relays with low time-dial settings. The coordinating-speed main curves are used for fault interrupters on main feeders and have a longer minimum response time and different shape to coordinate with tap-interrupter curves. Coordinating-speed curves have phase-overcurrent and ground-overcurrent settings. If desired, the ground-overcurrent August 23, 2010 S&C Electric Company Specification Bulletin 681-31
Conditions of Sale Continued setting can be turned off. (A ground-overcurrent setting is not available when the control is programmed for singlepole tripping of the fault interrupters.) These curves can be tailored to the application using a variety of instantaneous and definite-time settings. Vista switchgear is considerably smaller than traditional air-insulated gear, and is available in several styles, so it can be installed exactly where needed. The standard mounting styles of switchgear are as follows: UnderCover Style When the UnderCover style is specified, the gear is provided with a stainless-steel tank and submersible wiring. Vault-Mounted Style Two versions of this style are available: Wet-Vault-Mounted Style is intended for vaults that are subject to periodic flooding and includes submersible wiring and electrical components. Dry-Vault-Mounted Style is intended for vaults that are not subject to periodic flooding and does not include submersible wiring and electrical components. When the Wet-Vault-Mounted Style is specified, a stainless-steel tank is furnished, suitable for mounting on the floor or wall of a vault. When the Dry-Vault-Mounted Style is specified, a mild-steel tank is furnished. Pad-Mounted Style When the pad-mounted style is specified, a mild-steel or, optionally, stainless-steel enclosure and tank are provided. Pad-mounted enclosures meet the requirements of ANSI C57.12.28 (enclosure integrity). The top of the pad-mounted enclosure is hinged on both sides for convenient access to the operating and termination compartments. A removable panel provides access to the elbows and cables and is secured by the overlapping padlockable top. A resilient closed-cell gasket on the enclosure bottom flange protects the finish from being scratched during installation and isolates it from the alkalinity of a concrete foundation. Enclosures are protected from corrosion by S&C s Ultradur Finishing System. APPLICATION NOTES: Fault Interrupter S&C Vista Underground Distribution Switchgear features either arc-spinning contacts ( kv, 12.5 ka symmetrical), vacuum fault interrupters for three-pole load switching and fault interruption through 25 ka symmetrical, or singlepole load switching and fault interruption through 12.5 ka symmetrical. Complete ratings for the fault interrupter, as applied in Vista switchgear, are shown in the table on page 3. In addition to the load-dropping ratings shown, the fault interrupter is capable of interrupting transformer magnetizing currents associated with the applicable loads, as well as line-charging and cable-charging currents typical for distribution systems of these voltage ratings. The duty-cycle fault-closing rating shown for the fault interrupter defines the ability to close the interrupter the designated number of times into the closed position or ground position against a three-phase fault as follows: Main Contacts The fault interrupter shall have the ability to close the designated number of times into a three-phase fault equal to rated value and interrupt the resulting short-circuit current. The fault interrupter shall remain operable and able to carry and interrupt its rated continuous current. Ground Contacts The fault interrupter ground switch shall have the ability to close the designated number of times against a three-phase fault equal to the rated value with the ground switch remaining operable and able to carry its rated fault-closing current. A Note on Single-Pole Switching In single-pole switching of ungrounded-primary three-phase transformers or banks (or single-phase transformers connected line-to-line), circuit connections or parameters may, in some cases, produce excessive overvoltages. In particular, for the following applications above 22 kv, single-pole switching by any means should be performed only under the conditions stated in italics: Switching unloaded or lightly loaded delta-connected or ungrounded-primary wye-wye connected threephase transformers or banks (or line-to-line connected single-phase transformers), rated 150 kva or less threephase, or 50 kva or less single-phase or of any kva rating when combined with unloaded cables or lines where maximum system operating voltage exceeds 22 kv. Single-pole switching should be performed only if each phase is carrying 5% load or more, or if the transformer or bank is temporarily grounded at the primary neutral during switching. Switching loaded or unloaded ungrounded-primary wye-delta connected three-phase transformers or banks alone or combined with unloaded cables or lines where maximum system operating voltage exceeds 22 kv. Single-pole switching should be performed only if each phase is carrying 5% load or more and if the lighting-load phase is always switched open first (or switched closed last); or if the transformer or bank is temporarily grounded at the primary neutral during switching. 2 S&C Specification Bulletin 681-31
Load-Interrupter Switch S&C Vista Underground Distribution Switchgear features load-interrupter switches for three-pole live switching of three-phase circuits. Complete ratings for the load-interrupter switch, as applied in Vista Switchgear, are shown in the table below. In addition to the load-dropping ratings shown, the switch is capable of interrupting transformer magnetizing currents associated with the applicable loads, as well as line-charging and cable-charging currents typical for distribution systems of these voltage ratings. For applications involving load current with high harmonic content (such as rectifier load currents), refer to the nearest S&C Sales Office. The dutycycle fault-closing rating shown for the switch defines the ability to close the switch into the closed or ground position the designated number of times against a three-phase fault equal to the rated value, with the switch remaining operable and able to carry and interrupt rated current.
