The Megger PSI-700A is a rugged, lightweight instrument used to determine the phase sequence or phase rotation of a three-phase system. It will also detect and identify an open phase.

The PSI-700A is simple to use. The operator connects thre leads to the system and a lamp will instantly indicate either ABC clockwise rotation or CBA counter-clockwise rotation. Three lamps will light to indicate that all phase voltages are present. If a phase is open, only one lamp will light and identify the open phase.
