    The interruption of current in oil circuit‐breakers is performed in oil by way of the dissociation product H 2 gas, and therefore the oil circuit‐breaker is classed as a gas circuit‐breaker. Oil circuit‐breakers are classified according to the volume of oil used: bulk‐oil and minimum‐oil circuit‐breakers. The main difference between bulk‐oil and minimum‐oil circuit‐breakers lies in the fact that minimum‐oil breakers
