This article provides an in-depth exploration of how circuit breakers function in substations, covering their types, components, operation, and significance, supplemented with examples for clarity. Circuit breakers perform two fundamental roles in substations: (1) interrupt high fault. . A circuit breaker in substation systems interrupts fault current to protect transformers, busbars, and grid assets while supporting protection coordination, maintenance planning, and long-term substation reliability. In a substation there are numbers of incoming and outgoing circuits each having its isolator, circuit breaker, transformers etc. When a fault occurs, it interrupts the flow of electricity instantly to protect other equipment from damage.
