Switchgear - Wikipedia an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply.

TRV capacitors for air-insulated switchgears (AIS) application 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.
