Annotation of standard text IEC 62146-1-ed.2.0-RLV :
IEC 62146-1:2026 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62146-1:2026 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. This document applies to grading capacitors falling into one or both of the following categories for: - mounting on air-insulated circuit-breakers. - mounting on enclosed circuit-breakers (for example immersed in insulating gas, in oil, etc.). The object of this document is: - to define uniform rules regarding performances, testing and rating; - to define specific safety rules; - to provide a guidance for installation and operation. This document does not apply to capacitors not directly associated with high-voltage alternating current circuit-breakers.
