| Abstract: | Circuit breakers are crucial components for power systems operation, since it forms one of the major elements of a protection system, which contribute to the detection and removal of faults in the switchgear. In this study, the performance of various types of circuit breakers was examined in Osogbo Power Holding Company of Nigeria (PHCN) equipment centre. Three dominants type were considered: SF6 (Sulphur hexafluoride circuit Breaker), VCB (Vacuum Circuit Breaker) and OCB (Oil Circuit Breaker). Based on the results and analysis carried out, the SF6 breaker has the highest performance rate in terms of number of operations with a minimum failure rate. SF6 however, has the highest reliability and availability compared to the others. |
