Mitsubishi Electric Power Products, Inc. (MEPPI) now introduces its latest evolution in circuit breaker technology, the Gas Switch and Circuit Breaker (GSB). The primary advantage of the GSB over the GCB is the space savings at the substation. The GSB uses the same proven dead-tank circuit breaker, but replaces the switches you are using now with ones insulated by SF6. The space required for the breaker maintenance ground switches and disconnect switches is reduced dramatically. The resulting product replaces the standard combination of GCB and air switches and places the same functions into one-third the length.
Substation expansion is now possible where it once was not. MEPPI's hybrid circuit breaker positions offer a 70% reduction in the length of a circuit breaker position including disconnect switches at voltages of 230kV-500kV.
