IEEE C37.011 - The Transient Recovery Voltage (TRV) is the voltage that appears across the terminals of a circuit breaker after a current interruption. This voltage may be considered in two successive time intervals: one during which a transient voltage exists (TRV), followed by a second during which a power-frequency voltage alone exists.
