Phase Rotation Tester

PRT200-sA Phase Rotation Tester is a solution to a simple, yet widespread problem among engineers and contractors. Simply put, phase rotation in a motor is the determining factor of the direction in which the motor spins.

For example, you have a 3-Phase power source and a motor and you connect the phases to the motor, the direction of rotation will be either clockwise or counter-clockwise. Reverse two of the phases and the motor will spin in the opposite direction. A simple concept which can be very damaging or dangerous if not connected in the right orientation. There are many agricultural applications which require frequently serviced electrical motors. A loss of time or money due to a phase orientation mix up is the last thing you need, especially when there is a simple way to test the phase orientation of these motors.

Phase Rotation Testers indicate the phase orientation (clockwise or counter-clockwise) which could mean the difference between a correctly operating piece of machinery and a potentially dangerous malfunction.
