Research Summary

A Generator Circuit Breaker (GCB) is a specialized circuit breaker designed to protect electric power generators and their associated electrical systems. Positioned between the generator and the main transformer, the GCB serves as a crucial component in high-voltage power generation installations. Its primary function is to disconnect the generator from the power grid in the event of faults, overloads, or other abnormal conditions that could potentially damage the generator or the connected electrical network. GCBs are engineered to handle the unique characteristics of generator currents, which can be considerably higher than those encountered in standard power distribution systems. These circuit breakers play a critical role in ensuring the safety and reliability of power generation by swiftly isolating the generator from the grid during emergencies, preventing cascading failures and minimizing the risk of extensive damage to the electrical infrastructure.
