IEC 62146-1:2026 RLV

Capacitors for high-voltage alternating current circuit-breakers - Part 1: General and grading capacitors

OVERVIEW

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.
