Amendment Standard - Active.This IEEE Standards product is part of the C37 family on Switchgear, Substations and Protective Relays. The transient recovery voltage needs to be modified when interrupting asymmetrical currents. The voltage rate R, the peak voltage E2 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.
