Overload, power spikes, short circuit, or ground fault are some of the common electrical faults against which circuit breakers work effectively. In distribution and transmission networks, the protective relays are sufficient. But in the power generation plants where a high magnitude of current flows through the network, specialized equipment is needed. Here, an MCCB or ACB panel won\u2019t withstand the extremely high current. So, a special type of equipment is installed there. Generator circuit breaker manufacturers<\/a> <\/strong>provide the essential protective mechanism that helps in protecting the expensive setup from damage due to high fault currents.<\/p>\n\n\n\n

What is a Generator Circuit Breaker<\/h4>\n\n\n\n

A generator circuit breaker (GCB) can be considered a switch in the power grid or a bridge between the generator and the step up transformer. These are vital for protecting generators and other critical equipment in power plants. For safe operations, the voltage, frequency, and phase angle must be aligned in the power grid and generator. When all the conditions are within safe limits, the circuit breaker remains closed. As soon as there is any power spike or fault on either side of the GCB, it closes the circuit immediately. The assembly contains a main circuit breaker, a surge arrester, an earthing switch, and a control cubicle.<\/p>\n\n\n\n
