ABSTRACT:
A switchgear operable to conduct or shut off the a.c. current to an a.c. load by use of a semiconductor switch. The switchgear is formed such that a common thyristor switch in serial connection with a switch is connected in parallel to a switch for each of capacitor banks, so that each capacitor bank is connected or disconnected to the a.c. power line in non-contact manner through the thyristor switch.
