    :bash: difference between switchgear and circuit breakers

    what is the difference between switchgear and circuit breakers and is there any difference between outdoor and indoor switchgear and circuit breakers ,

    and how would you differentiate between switch yard and substation and grid station .

    thanks

    Wikipedia:


    Switchgear: is the combination 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."


    Circuit Breaker: is an automatically operated electrical switch designed to protect an electricalcircuit from damage caused by overload or shortcircuit. Its basic function is to detect a fault condition and interrupt current flow.

    Actually circuit Breaker is an automatically operated electrical switch designed to protect an electricalcircuit from damage caused by overload or shortcircuit. Its basic function is to detect a fault condition and interrupt current flow.
    And switchgear is the combination 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."

    There is one other difference to consider too. Switchgear is designed to be regularly operated whereas circuit breakers are not.

    A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to operate immediately after detection of a fault condition by the relay and, by interrupting continuity, to immediately discontinue electrical flow. Switchgear is the combination of electrical disconnect switches and 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 fault downstream. This type of equipment is directly linked to the reliability of the electric supply.
