high-voltage switch electrical equipment maintenance

Jan 12, 2020The low voltage switchgear involves many devices like power circuit breakers, MCBs, aux. relays, CTs, VTs etc. and of course at the end – enclosures (indoor or outdoor type). The frequency of inspection and maintenance of low voltage switchgear should be 3-6 months when new equipment is installed and 1-2 years for existing equipment.

  • Switchgear - Wikipedia

    In 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.
