Phase Sequence Indicator

The K-7-1 Phase Sequence Indicator indicates the order of succession in time of the different voltage peaks of a multi-phase supply. The K-7-1 is used in connection with the making of three-phase circuit installations or alterations, and replacement installations of motors and generators. It can be used for making continuity tests of circuits of poly-phase systems. It's also valuable in making connections of power-factor meters, voltampere meters, watt and watthour meters and relays.
