A circuit breaker in substation is a key component in electrical power systems, designed to interrupt the flow of electricity when a fault occurs, such as a short circuit or overload. Depending on system design, these devices can operate manually or automatically and come in various types, including air, vacuum, oil, and SF₆ gas.
The substation would be a combination of switching, controlling, and voltage step-down equipment arranged to reduce sub-transmission voltage to primary distribution voltage for residential, commercial, and industrial loads. Power substation consists of: The main equipment in Fahari substation consist of:
Power substation consists of: The main equipment in Fahari substation consist of: To step down the 33kV primary voltage to 11kV suitable for distribution purpose. One 33kV/0.415 auxiliary transformer was also needed to supply the substation with reliable AC power. Circuit breakers were needed so as to disconnect and isolate the faulted section.
Example: In a modern urban substation where space is limited, a hybrid circuit breaker might be used to protect the main incoming feeder. The hybrid design allows for compact installation while providing reliable fault protection and efficient arc quenching.
