Item #PSI-700A, Megger Phase Sequence Tester PSI-700A

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.

  • Indicates clockwise or counterclockwise rotation
  • Detects open A, B or C phase
  • No moving parts, batteries or binding posts
  • No power source required
  • Rugged insulated enclosure
  • Canvas carrying case included
