Abstract

IEC 62146-1:2026 is available as IEC 62146-1:2026 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the 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.
