Common use of Circuit Breakers Clause in Contracts

Circuit Breakers. Each of the three (3) breakers shall use reclosing and redundant breaker failure protection. ‘A’ and ‘B’ package breaker failure protection will be performed by two (2) SEL 351-6 relays for each breaker at the station (totaling six (6) breaker failure relays). Reclosing will be performed by one (1) SEL 351-6 relay for each breaker in the station (totaling three (3) reclosing relays). Direct Transfer Trip (“DTT”) will be required between the ▇▇▇▇▇▇▇▇ Road Station and the Dunkirk and New Gardenville stations for breaker failure protection. Lines 73 to Dunkirk and Line 84 to New Gardenville will use two (2) different relay packages. The ‘A’ package will use RFL 9780 FSK carrier equipment and the ‘B’ package will use the mirrored bit functionality of the SEL 351-6 relay and the RFL IMUX 2000. The Generator Tie Line to the Ball Hill Collector Substation will use the functionality of the line differential relays. DTT receive from the Ball Hill Collector Substation will be required for breaker failure. The functionality of the line differential relay will be used to transmit the signal. A and B transfer trip receive relays to trip the Generator Tie Line breakers is required.
