This standard specifies the terms and definitions, usage conditions, technical performance requirements, testing, marking, packaging, storage, transportation, and acceptance of high-voltage parallel capacitors. This standard applies to capacitors connected in parallel to AC power systems with a rated frequency of 50Hz and a rated voltage above 1kV, used to improve power factor. This standard does not apply to the following capacitors: - self-healing type capacitors—— Assembled capacitor—— Series capacitors for power systems—— Capacitors for induction heating devices—— A capacitor used under AC voltage superimposed with DC voltage. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document.
