IEC 62146-1:2026
Capacitors for high-voltage alternating current circuit-breakers - Part 1: General and grading capacitors
OVERVIEW
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.
