Thyristor (SCR) Circuit Breaker

In simple circuit breaker system relays are used to control on – off. In these days thyristors are used for the same system. The property of a SCR is to latch, when it can be triggered by an 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.
