Abstract :
High-speed ground switches offer a means of power system protection approching that of a circuit breaker, yet are less expensive than fuses. To obtain this protection requires an extremely high degree of reliability and speeds of operation compatible with circuit breakers. Described here is a new ground switch capable of 6.7-cycle closing time at 230 kv to 2.4 cycle closing time at 69 kv. Closing time is measured from initiation of closing signal to ground switch contact make.
