MindCore HSF series of High Speed Fault switches is designed for rapid speed application of a solid ground fault to the power system. A fault initiating switch is a device, when actuated by protective relays will operate to apply a deliberate fault to a power system. Its principal application is in transformer fault protection, when used in conjunction with an automatic motor operated disconnect switch, it will economically replace a circuit breaker in the transformer station.
