Types of Circuit Breaker - Circuit Globe » All about ... voltage breaking capacity of the HVDC circuit breaker is nearly 33KV, and for the current, it is 2KA. The main problem of the HVDC circuit breaker is that the DC is unidirectional and hence there is no zero point in the DC system. The fault current in the HVDC circuit breaker should be reduced to zero by using some external methods.

Transformer - Wikipedia(electrical)A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. . Electrical energy can be transferred between ...
