IEEE PC37.012

IEEE Draft Guide for the Application of Capacitive Current Switching for AC High-Voltage Circuit Breakers Above 1000 V

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 breakers for different network conditions and different capacitive loads (capacitor banks, cables, transmission lines, and filter banks) is treated.

IEEE Guide for the Application of Capacitance Current Switching for AC High-Voltage Circuit Breakers Above 1000 V Amendment 1

Covered in this amendment are changes in di/dt limitations for non-oil circuit breakers. A section has been added describing possible delayed current zeros when doing a rapid close–open of a line circuit breaker (CO) when shunt reactors are connected to a line or cable. Some minor errors have been corrected and references have been updated.
