#EEE - Transient recovery voltage

  1. 1. Transient Recovery Voltage
  2. 2. • Finally when the arc get extinguishes a high frequency voltage transient appears across the contacts. This occurs due to contacts are nearer to each other. • This high frequency transient tries to restrike the arc hence it is called transient recovery voltage. • Transient recovery voltage affects the behavior of circuit breaker. • This voltage appears immediately after final interruption. • This causes high dielectric stress between contacts. • If dielectric stress is less then arc is restrikes.
