switchgear is nothing but indoor version of switchyard.
its main function is switching operations in electrical
ckts.they r used to de-energize equipment to allow work to
be done and also to clear faults downstream.
in switch gear not all provisions but few are provided as a switch yard like.....

as switch gear system is panel based system so has some limitations and other than that mainly used for meter displays purpose like V,I,p.f,kwh,frequency etc....
