A large utility in the southwest U.S. contracted with S&C’s Power Systems Services Division to study ways to improve their system reliability. One concern was a substation with four 138/13.8-kV transformers.

The existing transformer protection scheme used the line-terminal circuit breakers and bus breakers to trip the entire high-voltage bus after a fault. The motor-operated air-break disconnect switch on the primary side of each transformer would then open, isolating its associated transformer. Only after the system operator located the faulted transformer could the disconnect switches on the unfaulted transformers be closed, followed by the line-terminal and bus breakers. Continue reading
