Abstract

Loads A B C D E in a sectionalised supply line are each provided with electric switch devices (A1-A2, B1-B2, C1-C2), adapted to open on dropout of control voltage eg line voltage beyond a predetermined time and to close when recovery control voltage lasts beyond a predetermined time. After control voltage dropout, because fault X opens S1, switches A1, B1, which first receive control voltage after automatic reclosure of S1 will be then blocked in the closed position, switches A2, B2, 8c having remained closed. Fault X causes S1 to reopen a second time whereupon A2 opens and that switch B2 nearest the fault opens and blocks open. Thus the second reclosure of S1 will supply power to loads A, B more rapidly because switches A1, B1 do not have to be reclosed. <IMAGE>
