Advantages Disadvantages of Oil Circuit Breakers. Oil circuit breakers are the oldest type of circuit breakers. The separating contacts of the oil circuit breakers are made to separate within the insulating oil which has better insulating properties than air. On the occurrence of the fault as the breaker contacts open under the oil, an arc is struck between the breaker contacts and the heat of the arc evaporates the surrounding oil and dissociates into a substantial volume of gaseous
