The oil also helps to prolong the life of the contacts by reducing wear and tear and preventing oxidation. During the normal operating conditions, the contact of the oil circuit breaker (OCB) is closed and carry the current. When the fault occurs in the system, the contacts of the breaker move apart, and an arc is struck between the contacts.
Energy storage systems, and in particular batteries, are emerging as one of the potential solutions to increase system flexibility, due to their unique capability to quickly absorb, hold and then reinject electricity.
