High-voltage circuit breakers used on transmission systems may be arranged to allow a single pole of a three-phase line to trip, instead of tripping all three poles; for some classes of faults this improves the system st…Mer

In electronics, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The most familiar form of switch is a manually operated el…Mer

In an electric power system, switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize eq…Mer

Oil Circuit Breaker a high-voltage AC electrical switch whose main contacts are located in a space filled with mineral (transformer) oil. Upon interruption of the electric circuit, an electric arc forms between the conta…Mer
