IEEE PC37.012/D5, November 2021 IEEE Draft Guide for the Application of Capacitance Current Switching for AC High-Voltage Circuit Breakers Above 1000 V
Institute of Electrical and Electronics Engineers (IEEE)
Scope
Guidance for the application of ac high-voltage circuit breakers switching capacitive currents is provided. The application guide addresses the general theory of capacitive current switching; and the notions of restrike, re-ignition, non-sustained disruptive discharge (NSDD). Voltage factors used for single-phase testing as substitute for three-phase testing are explained. Application of circuit b...
