Disconnect Switches Sample Clauses

Disconnect Switches. The 230 kV Disconnect Switch will be worm gear operated, 230 kV, three phase, vertical break, 900 kV BIL, 2000A, 60 Hz. The 34.5KV disconnect switch will be a group operated motor disconnect switch, 4000A, 3-phase, vertical break, 200KV BIL,60 Hz There are a total of 48 swtiches for the eight 38kV breaker positions .Each 38 kV circuit breaker will have six, single phase, hook-stick disconnect switches rated 1200A, 38 kV. These switches are manually operated via a hot-stick by a substation operator.
Disconnect Switches. Four (4) 2000 A 40 kA horizontal-mounted group-operated disconnect switches
Disconnect Switches. There shall be two manually operated disconnect switches in the ring bus for each circuit breaker and one disconnect switch for each circuit entering or leaving the substation. The manual switches shall be used for isolation of circuit breakers and incoming/outgoing lines. The switches are not required to have load break capability. The switches shall be group‑operated. The switches shall have auxiliary contacts installed for remote status. The configuration of the switches shall be arranged in a manner that maintains the required air gap clearances in the open position. ANSI phase spacing shall be maintained for all switches.
Disconnect Switches. Transfer switches.
Disconnect Switches. A. Fusible Switch Assemblies: NEMA KS 1; FS W-S-865; quick-make, quick-break, load interrupter enclosed knife switch with externally operable handle interlocked to prevent opening front cover with switch in ON position. Handle lockable in OFF position. Square-D H series. B. Nonfusible Switch Assemblies: NEMA KS 1; Type HD; quick-make, quick-break, load interrupter enclosed knife switch with externally operable handle interlocked to prevent opening front cover with switch in ON position. Handle lockable in OFF position. Square-D H series. C. Enclosures: NEMA KS 1; as indicated on Drawings.
Disconnect Switches. Fused or non-fused, heavy duty type, horsepower rated for motor loads. Enclosure: NEMA 1, indoor: NEMA 3R, outdoor.
Disconnect Switches. Tester shall conduct the following Commissioning Tests on the Disconnect Switches on each Facility Portion: Perform visual and mechanical inspections listed in the latest revision of the ▇▇▇▇ Acceptance Testing Specification section 7.5.1.3, including the following: Compare equipment nameplate data with drawings and specifications. Inspect physical and mechanical condition. Inspect anchorage, alignment, grounding, and clearances. Perform mechanical operator tests in accordance with Manufacturer’s published data, if applicable. Verify correct operation and adjustments of motor operator limit switches and mechanical interlocks, if applicable. Verify correct blade alignment, blade penetration, travel stops, arc interrupter operation, and mechanical operation. Verify operation and sequencing of interlocking systems. Verify correct operation of all indicating and control devices, if applicable. Record as‐found and as‐left operation counter readings. Verify switch handle and operator platform grounding is adequate, for the switch operator grounding. Perform electrical tests listed in the latest revision of the ▇▇▇▇ Acceptance Testing Specification section 7.5.1.3, including the following: Perform resistance measurements through bolted connections with a low‐resistance ohmmeter. Perform contact‐resistance test across each switchblade. Perform insulation‐resistance tests for one minute on each pole, phase‐to‐phase and phase‐to‐ ground with switch closed, and across each open pole. Apply voltage in accordance with Manufacturer’s published data. Perform a dielectric withstand voltage test on each pole with switch closed. Test each pole‐to‐ ground with all other poles grounded. Test voltage shall be in accordance with Manufacturer’s published data. Verify alarm and/or auxiliary contacts operate as expected.
Disconnect Switches. 1. Design guidance for Infrastructure described in this section is provided in HFDG Section 6.2.14 – “Electrical Switches”. 2. The Design-Builder must provide disconnect switches mounted in a separate cubicle in the ▇▇▇▇ ▇▇▇▇▇▇▇▇ OMF: a. ensure that each disconnect switch has a solid copper blade with silver plated contacts that is manually operated, single-pole and jaw-pressure-type, and an insulated operating handle; b. the disconnect switches must be non-load break switches; and c. design each positive disconnect switch with electrical interlocking feature to prevent operation under load.

  • Disconnection Upon termination of this Agreement, Developer and Connecting Transmission Owner will take all appropriate steps to disconnect the Developer’s Large Generating Facility from the New York State Transmission System. All costs required to effectuate such disconnection shall be borne by the terminating Party, unless such termination resulted from the non-terminating Party’s Default of this Agreement or such non-terminating Party otherwise is responsible for these costs under this Agreement.

  • Switching All of the negotiated rates, terms and conditions set forth in this Section pertain to the provision of local and tandem switching.

  • System Upgrades The Connecting Transmission Owner shall procure, construct, install, and own the System Upgrade Facilities and System Deliverability Upgrades described in Attachment 6 of this Agreement. To the extent that design work is necessary in addition to that already accomplished in the Class Year Interconnection Facilities Study for the Interconnection Customer, the Connecting Transmission Owner shall perform or cause to be performed such work. If all the Parties agree, the Interconnection Customer may construct System Upgrade Facilities and System Deliverability Upgrades. 5.2.1 As described in Section 32.3.5.3 of the SGIP in Attachment Z of the ISO OATT, the responsibility of the Interconnection Customer for the cost of the System Upgrade Facilities and System Deliverability Upgrades described in Attachment 6 of this Agreement shall be determined in accordance with Attachment S of the ISO OATT, as required by Section 32.3.5.3.2
