Withstand - 555kV; Rated BIL in the pressurized SF6 housing - 1050kV; Rated BIL across any open contacts – 1300kV; Rated Test Voltage Withstand for Pothead Compartments – 540kVDC for 15 minutes. All electrical components associated with installation of new 345kV feeder, such as disconnect switches, pothead, and potential transformers will be SF6 GIS design. The GIS bus section will include 345kV metering grade (0.3 ANSI revenue metering accuracy) potential transformers to replace an existing CCPD connected to 345kV bus section No.10. The new GIS section will be designed to have transition compartments between existing ITE GIS bus and new 345kV potential transformer assembly. The GIS bus section will be designed to provide the transition compartments between existing ITE gas insulated bus and new bus and pothead compartments. Transition compartments shall be supplied, as required by Connecting Transmission Owner’s specifications. Also, the new pothead compartments design shall incorporate an additional 3 single phase operated test disconnect switch in order to provide sufficient isolation to the existing 345kV GIS equipment during the high voltage testing of the new 345kV solid dielectric feeder. New pothead compartments shall accept 400kV solid dielectric cable terminations designed to IEC TS 60859 specifications maintaining the existing feeder outlets, feeder disconnect, and ground switch. The GIS equipment supplier shall provide platforms to the GIS equipment view ports, gas pressure gauges, and related equipment to ensure easy future safe personnel access and maintenance. The platforms design shall adhere to the OSHA requirements. Prior to the purchase of the GIS equipment, Developer has the option to purchase and have Connecting Transmission Owner install one (1) 3 phase Disconnect Switch for future expansion of ring bus. The existing oil pipe type cable conduit in the cable tunnel will be removed in order to provide the route required for the DAF installation and routing. The following are details regarding the protection and control equipment required at the West 49th Street Substation: New metering and relay protection current transformers will be installed on the new cable termination stand for Developer’s cable. The existing structural steel cable termination and accessories stand will be replaced to accommodate the Developer’s new solid dielectric cable and provide mounting abilities for necessary relay protection current transformers. Four relay protection panels will be installed consisting of new control, supervisory and protection equipment along with all wiring, terminations and raceways. The existing control room layout will be modified to provide space for the installation of four relay panels associated with Developer’s new 345kV feeder. The existing zones of relay protection will be modified and new zones of relay protection will be established in compliance with Connecting Transmission Owner’s Engineering Specifications and NPCC Bulk Power System Protection requirements. To the extent applicable for relay protection located outside the New York Control Area, RFC requirements may also apply to such relay protection.
