Two 345kV circuits feeding group operated air break (GOAB) switch mounted on A-frame dead-end structures. 2000A 345kV high voltage circuit breakers feeding owner furnished 120MVA, 345/13.8kV Hitachi transformers. Overhead distribution to (12) individually mounted 3000A, 15kV medium voltage circuit breakers connected to an outdoor control enclosure with SEL Relays.
The second one includes two 345kV circuits feeding group operated air break (GOAB) switch mounted on A-frame dead-end structures. 2000A 345kV high voltage circuit breakers feeding owner furnished 143MVA, 345/13.8kV Pennsylvania Transformer Technology transformers. Overhead distribution to (10) individually mounted 3000A, 15kV medium voltage circuit breakers connected to an outdoor control enclosure with SEL Relays.
