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.
A substation circuit breaker has three critical life stages: initial installation, maintenance and testing, and end-of-life. Following proper procedures at all of these stages will extend the life and enhance the efficacy of your circuit breakers.
Substation circuit breakers must comply with national and international reliability and safety standards, such as those set out by the American National Standards Institute (ANSI) or the International Electrotechnical Commission (IEC).
Substation circuit breakers are often exposed to harsh conditions, including extreme weather, dust, moisture, and temperature fluctuations. Their design must accommodate these conditions in order to maintain function and reliability.
