Superseded Standard

IEEE C37.012-2005

IEEE Application Guide for Capacitance Current Switching for AC High-Voltage Circuit Breakers

Guidance for the application of ac high-voltage circuit breakers for capacitance current switching is provided. The document addresses the general theory of capacitance current switching, the notion of restrike, reignition, NSDD and voltage factors are explained. Application of circuit breakers for different network conditions and different capacitive loads (lines, cables, capacitor and filter banks) is treated.

C37.012-2022

IEEE 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 general theory of capacitive current switching and the notions of restrike, reignition, and nonsustained disruptive discharge (NSDD) are addressed in the application guide. Voltage factors used for single-phase testing as a substitute for three-phase testing are explained. The application of circuit breakers for different network conditions and different capacitive loads (capacitor banks, cables, transmission lines, and filter banks) is discussed.

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


C37.012-2014

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

Guidance for the application of ac high-voltage circuit breakers is provided. The application guide addresses the general theory of capacitance current switching; and the notions of re-strike, 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.

C37.012a-2020

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.
