What is Oil Circuit Breaker |

An oil circuit breaker (OCB) is a type of circuit breaker that uses oil as the insulating and arc-quenching medium between the contacts. When the circuit breaker is closed, the contacts are immersed in the oil, which acts as an insulator and prevents the current from flowing between them. When the circuit breaker is opened, the contacts are
