Abstract
Abstract A power supply arrangement, which includes buses sectionalized by a switch, further includes feeders and service lines. Connected in series with the sectionalizing switch is a quick-acting switch apparatus closing the network, in case of a fault in one of the feeders, during the first cycle of hunting of the electromotors until the phases of such electromotors are in phase opposition with another feeder to which the electromotors are now connected by the quick acting switch apparatus.
