WebCT ratio formula: CT ratio = I (P) / I (s) ————-1. Example: 1000:1. Here 1000 means it is a primary current and 1 means secondary current. Also, we can have rewritten as 1000/1. CT secondary current will be always 1 or 5 to get easy calculation as well as we can create small rating secondary circuits to withstand up to 5 Amps. WebIn power distribution, we need circuit breakers at different levels. Depending on the current carrying capacity, breaking capacity and other functions, we select a suitable circuit breaker according to our needs i.e. VCB, ACB (Air Circuit Breaker), MCCB and then MCB , this is a common hierarchy being followed in power distribution systems.
