IEC 62146-1 Ed. 1.0: Grading capacitors for high-voltage alternating current circuit-breakers
Abstract
This standard is applicable to the grading capacitors used on circuit breakers to control the voltage distribution across the individual interrupting chambers.The capacitors are also used to equalise the voltage distribution across the interrupting chambers both during circuit breaker opening and closing operations.Grading capacitors can also be used in parallel on single break circuit breakers to improve the circuit breaker capability.
