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. Safety or protection of Air circuit breaker (ACB).
