This file contains photographs and technical documentation of electrical switchgear equipment used in a main substation facility.

The document displays detailed images and specifications for S&C VISTA® Underground Distribution Switchgear units designated for Loop 1, with identical gear specified for Loop 2, Loop 3, and 5B1. The Loop 1 switchgear nameplate indicates the following key ratings: 15.5 kV maximum, 95 kV basic impulse level, 600 amperes continuous, 25,000 amperes short-circuit rating, 600 amperes fault interrupters, and 48,060-cycle duty-cycle fault-closing time. The equipment includes a Schneider Electric PowerLogic ION7650 power measurement device (Model S7650A0C0B6A0A0A, Serial LJ-1501A633-05) configured for 60 Hz operation with current inputs of 0.05-20A and voltage inputs of 57-347V. Additional components shown include a Cutler-Hammer Westinghouse Vacuum Circuit Breaker VCP-W and a Greenwood Assemblies power/mini module rated for 5/15kV at 250/500/750MVA. The breaker specifications include Type 150VCP-4500 with a rated maximum voltage of 15 kV, 1,200 amperes continuous current, and 18 kA short-circuit current rating at 60 Hz frequency.
