  • TRV Capacitors - AIS

    TRV Capacitors - AIS

    In air-insulated switchgears (AIS), transient recovery voltage (TRV) capacitors are installed phase-to-ground. They decrease the oscillation frequency and the rate of rise of recovery voltage (RRRV) of TRV, which occurs during initiation or interruption of current flow. TRV capacitors are thus installed to increase breaking power of the circuit breaker.

  • TRV Capacitors - GIS

    TRV Capacitors - GIS

    Gas-insulated switchgear (GIS) circuit breakers for tough environments with extreme temperature variations, dust, pollution or confined space may use transient recovery voltage (TRV) capacitors. They decrease the oscillation frequency and the rate of rise of recovery voltage (RRRV) of TRV which occurs during initiation or interruption of current flow. TRV capacitors are thus installed to increase breaking power of the circuit breaker.

  •  RC-Grading Capacitors for HVDC Bypass switchgear

    RC-Grading Capacitors for HVDC Bypass switchgear

    Resistance or combination of resistance and capacitance compose the RC-grading capacitors; they are installed on high-voltage bypass multi-break circuit breakers.

  • Grading Capacitors - AIS

    Grading Capacitors - AIS

    In air-insulated switchgears (AIS), grading capacitors ensure a uniform distribution of the voltage across the breaking chambers of the live tank circuit breaker.
