What is meant by switch gears in electrical
engineering?
Answer:Switchgear is the generic name for transmission and distribution
equipment designed control, disconnect, and protect an electrical system.
Switchgear includes circuit breakers, fuses, and isolators
(US term: disconnectors). As well as being used to control circuits by
opening or closing those circuits, circuit breakers are designed to interrupt
and to close onto electrical faults so must incorporate means of
extinguishing the arcing associated with such faults. Circuit breakers,
therefore, have a essential role in responding to protection systems. Isolators
are non-load breaking switches, designed to isolate equipment (including
circuit breakers) from high voltages, so that the equipment can be maintained.
