IEEE STANDARD

C37.081a-1997 - Supplement to IEEE Guide for Synthetic Fault Testing of AC High Voltage Circuit Breakers Rated on a Symmetrical Current Basis

Description: The transient recovery voltage needs to be modified when interrupting asymmetrical currents. The voltage rate R, the peak voltage E/sub 2/ and the rate of change of current di/dt all change with the asymmetrical current zero. Guidance is provided on how to make these corrections when compared to the symmetrical case.
