Transient recovery voltage

Examples of TRV waveshapes
Figure 1 - Recovery voltage in case of a capacitive load
Figure 2 - Voltages on terminals of the first pole that clears three-phase capacitive currents in a system with isolated neutral
Figure 3 - Evolution of voltages with restrike occurring a half cycle after current interruption, in the case of single-phase capacitive current switching

A transient recovery voltage (or TRV) for high-voltage circuit breakers is the voltage that appears across the terminals after current interruption. It is a critical parameter for fault interruption by a high-voltage circuit breaker, its characteristics (amplitude, rate of rise) can lead either to a successful current interruption or to a failure (called reignition or restrike).
