  • Oil Circuit Breaker(classification of circuit breakers)

    Apr 13, 2017OIL CIRCUIT BREAKERS In such circuit breakers, some insulating oil (e.g., transformer oil) is used as an arc quenching medium. The contacts are opened under oil and an arc is struck between them. The heat of the arc evaporates the surrounding oil and dissociates it into a substantial volume of gaseous hydrogen at high pressure.
