Thyristor Circuit Breaker

THYRISTOR CIRCUIT BREAKER {CURRENT LIMITING} In simple circuit breaker system relays areused to control on - off. In these days thyristorsare used for the same system. The property ofa SCR is to latch, when it can be triggered byan input gate current, when its anode is +ve than its cathode. The SCR get turn off by breaking the anode current producing anode current below a value IH.
