Capacitors for high-voltage alternating current circuit-breakers - Part 1: General and grading capacitors
Abstract
This part of IEC 62146 includes generalities of capacitors used on alternating current circuit-breakers and introduces specifications for grading capacitors. Regarding grading capacitors, their function is to control the voltage distribution across the individual interrupter units of a multi-break circuit-breaker. Capacitors can also be used in parallel to the interrupter unit on single break circuit-breakers to modify the Transient Recovery Voltage (TRV). This TRV capacitor application is covered by IEC 62146 2:2023. Capacitors for high-voltage alternating circuit breakers are sub-components for the circuit-breaker and are specified in accordance with the circuit-breaker specifications according to IEC 62271 1, IEC 62271 100, and if applicable to IEC 62271 203.
