high-voltage Recovery system

Oct 23, 2020The dielectric recovery of the arc quenching medium and rate of rising of transient recovery voltage has great influence on the performance of the circuit breaker used in high voltage switchgear system. In an air blast circuit breaker, once ionized air is de-ionized very slowly, thus air takes a long time to recover dielectric strength.

  • Transient Recovery Voltage and Its Effect on a Circuit

    Jun 02, 2020One problem that is pervasive in the power grid and not well understood is called the Transient Recovery Voltage (TRV). When a short-circuit due to a fault in high voltage or medium voltage system is switched-out by a circuit breaker, the voltage across the breaker poles rapidly increases; as high as twice the operating voltage.
