Organization: IEC
Publication Date: 1 September 2013
Status: inactive
Page Count: 76
ICS Code (Power capacitors): 31.060.70
ICS Code (Capacitors in general): 31.060.01
scope:

This part of the IEC 62146 series is applicable to grading capacitors used on circuit-breakers. Their function is to control the voltage distribution across the individual interrupter units of a multi-break circuit-breaker.

Grading capacitors can also be used in parallel to the interrupter unit on single break circuitbreakers to modify the Transient Recovery Voltage (TRV).

The grading capacitor is a sub-component for the circuit-breaker and shall be specified in accordance with the circuit-breaker specifications.

This standard 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 SF6, in oil, etc.). The testing for each of the above applications is in some cases different.

The object of this standard is:

- to define uniform rules regarding performances, testing and rating;

- to define specific safety rules;

- to provide a guidance for installation and operation.
