Air circuit breaker in 6kV relay protection
Air Circuit Breakers (ACBs) are heavy-duty circuit protection devices used for main LV incomer, generator output, and bus-coupler protection in installations with current ratings from 800 A to 6300 A. They interrupt fault current in air, using arc chutes and blowout devices. An air circuit breaker is a low-voltage circuit breaker designed to protect high-current power distribution systems against overloads, short circuits, and other electrical faults. The circuit breakers are suitable for use in electrical distribution networks with AC 50Hz/60Hz, rated. In 6kV power plant distribution systems, arc flash protection relays serve as a critical last line of defense, bridging the safety gap left by traditional overcurrent protection, which often suffers from a 100ms–300ms coordination delay. 6kV systems are given in Code of Practice (CP) 373. 6kV (excluding primary substations) and 400V networks is covered by CP331, which details standard relay.
