OS GSO IEC 62146-1:2016 Scope

IEC 62146-1:2013+A1:2016 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 circuit-breakers 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. Keywords: grading capacitors, circuit-breakers This consolidated version consists of the first edition (2013) and its amendment 1 (2016). Therefore, no need to order amendment in addition to this publication.
