Question

difference between active recovery voltage and restriking voltage

Answer 1

Recovery voltage is the voltage at the terminal of CB, after the circuit interruption. Restriking voltage is what appears across the contacts at current zero during arc period & will have higher frequency. ... [Define Restriking Voltage.

Answer 2

Difference between active recovery voltage and restriking voltage -

• Active Recovery Voltage - It may be defined as the instantaneous recovery voltage at the instant of arc extinction.
• Restriking voltage - The transient voltage that appears across the circuit breaker contacts at the instant of arc extinction is called restriking voltage. It is measured in peak value. Restriking voltage is the transient voltage appearing across the breaker contacts immediately after the opening of breaker contacts.
