Manual Vista® Underground Distribution Switchgear Vista® Green Underground Distribution Switchgear Outdoor Distribution (15.5 kV through 38 kV)

Conditions of Sale STANDARD: The seller’s standard conditions of sale set forth in Price Sheet 150 apply, except as modified under the “Special Warranty Provisions” section on “Special Warranty Provisions” on page 4.

SPECIAL TO THIS PRODUCT:

INCLUSIONS: Vista Underground Distribution Switchgear features load-interrupter switches for switching 600- or 900-ampere main feeders and microprocessor-controlled arc-spinners or vacuum fault interrupters for switching and protection of 600- or 900-ampere main feeders and 200-, 600-, or 900-ampere taps, laterals, and subloops.

These elbow-connected components are enclosed in a gas-insulated gas-tight (SF6) or hermetically sealed (CO2 mix) welded-steel tank, completely protected from the environ-ment. The switchgear is available with up to six ways (bus terminals, switches and/or fault interrupters) in ratings through 38 kV and 25 kA symmetrical. Standard Vista switchgear products ship with sulfur hexafluoride (SF6) insulating gas. The new optional Vista Green Underground Distribution Switchgear ships with a dielectric gas mixture of CO2 and C4-FN insulating gas instead of SF6. See pages 6 and 7 for details on how to build Vista and Vista Green switchgear catalog numbers.

The three-position (CLOSED-OPEN-GROUNDED) load-interrupter switches are manually operated and provide three-pole live switching of 600- 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, arc-spinning contacts (15.5-kV, 12.5-kA symmetrical SF6 gas-insulated models only), or vacuum interrupters in series with manually operated three-position (CLOSED-OPEN-GROUNDED) disconnects (15.5-kV, 25-kA symmetrical, and all 29-kV and 38-kV models) for isolation and internal grounding of each phase. See Table 1 on page 8 for the available Vista and Vista Green switchgear ratings.

Fault interrupters provide three-pole load switching and fault interruption through 25 kA symmetrical or single-pole 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 interrupt-ers, 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 (SF6 models only) or 600- or 900-ampere bushings (as specified). Bushing and bushing-well interfaces are in accordance with IEEE Standard 386 to accept all standard insulated connectors and inserts.

In addition, Vista Underground Distribution Switchgear has been certified as arc resistant per IEC 62271-200 for fault currents up to 12.5 kA symmetrical for 15 cycles (25 kA symmetrical for units rated 25 kA short circuit). Arc resis-tance is standard for the pad-mounted and UnderCover™ styles. For the vault-mounted style, 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.

Manual Vista® Underground Distribution Switchgear Vista® Green Underground Distribution Switchgear

When optional voltage indication is specified, all routine operating tasks—switching, voltage testing, and ground-ing—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 feedthru insert eliminat-ing the need for difficult cable handling or parking stands.

Vista Overcurrent Control 2.0 Fault interruption is initiated by a programmable over-current control housed in a watertight enclosure. The control is programed using a personal computer connected to the control via a USB cable (Type A to Type A). The control receives both sensing and control inputs from current transformers. No batteries are needed for the Vista overcurrent control 2.0.

Current transformers provide power and input signals.

The control features a variety of time-current characteristic (TCC) curves—standard “E,” “K,” and “T” speed curves, Vista coordinating-speed tap and main curves, and relay curves per IEEE C37.112-2018.

Coordinating-speed tap curves are used for fault inter-rupters feeding subloop taps and are specificallydesigned 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 a different shape to coordinate with tap-interrupter curves. Coordinating-speed curves have phase-overcurrent, ground-protection, negative-sequence fault, and sensitive-earth fault settings.

The coordinating-speed tap and main curves, as well as IEEE and IEC relay TCC curves, can be tailored to the application using a variety of TCC curve based and definite-time settings. Ground-protection, negative-sequence fault, and sensitive-earth fault settings are also available.

Vista Switchgear Styles:

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. The wet-vault mounted style is intended for vaults subject to periodic flooding and includes submersible wiring and electrical components. The dry-vault mounted style is intended for vaults not subject to periodic flooding and does not include submersible wiring and electrical components. A stainless steel tank suitable for mounting on the floor or wall of the vault is furnished with both wet- and dry-vault mounted styles.

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. The roof of the enclosure is sloped outward to ensure water flows away from the switchgear.

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 founda-tion. Enclosures are protected from corrosion by S&C’s Ultradur® II Outdoor Finish.

Vista® Green Underground Distribution Switchgear

Application Notes:

Fault Interrupter Vista Underground Distribution Switchgear features either arc-spinning contacts (15.5-kV, 12.5-kA symmetrical SF6 gas-insulated models only) vacuum fault interrupters for three-pole load switching and fault interruption through 25 kA symmetrical, or single-pole load switching and fault interruption through 12.5 kA symmetrical.

Complete ratings for the fault interrupter, as applied in Vista switchgear, are shown in Table 1 on page 8.

In addition to the load-dropping ratings shown, the fault interrupter is capable of interrupting transformer magnetiz-ing 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 Grounded position against a three-phase fault as follows:

• Main Contacts. The fault-interrupter has 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 remains operable and able to carry and interrupt its rated continuous current.

• Ground Contacts. The fault interrupter ground switch has 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 three-phase transformers or banks (or line-to-line connected single-phase transformers), rated 150 kVA or less three-phase, 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 trans-former or bank is temporarily grounded at the primary neutral during switching.)

Vista® Green Underground Distribution Switchgear

Load-Interrupter Switch 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 Table 1 on page

8. In addition to the load-dropping ratings shown, the switch is capable of interrupting transformer magnetiz-ing 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 duty-cycle fault-closing rating shown for the switch defines the ability to close the switch into the Closed or Grounded position the desig-nated 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.

EXCLUSIONS: Three-phase units listed in Table 2 on pages 9 through 14 do not include the switchgear style, optional features, or accessories listed in Tables 3, 4, and 5 on pages 15 through 21.
