    en.wikipedia.org/wiki/Switchgear

    Tram switchgear This circuit breaker uses both SF 6 and air as insulation. In an electric power system, a 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 ...

    en.wikipedia.org/wiki/Substation

    Low-profile substations may be specified in suburban areas where appearance is more critical. Indoor substations may be gas insulated substations (GIS) (at high voltages, with gas insulated switchgear), or use metal-enclosed or metal-clad switchgear at lower voltages. Urban and suburban indoor substations may be finished on the outside so as to ...

  8. Dielectric withstand test - Wikipedia

    en.wikipedia.org/wiki/Dielectric_withstand_test

    An insulation test set; in this pattern, a hand-cranked generator provides the high voltage and the scale is directly calibrated in megohms. Voltage withstand testing is done with a high-voltage source and voltage and current meters. A single instrument called a "pressure test set" or "hipot tester" is often used to perform this test.
