Martindale PSI4000 Phase Rotation Tester
When it comes to verifying the phase sequence or rotation of three phase circuits Martindale have a number of solutions, and by far the best solutions from a safety point of view are the battery-operated PSI4000 and PSI4300. These are known as non-contact testers because the insulated clips work by induction and can take a reading through the insulation of each phase conductor so reducing the risk of coming into contact with live parts.
(PSI4000 carries out measurements via colour-coded inductive CT’s, as opposed to probes or croc clips providing the safest way to conduct a phase sequence check)
Simply connect the high-quality colour-coded clips in the L1, L2 and L3 order, turn the instrument on and a buzzer provides an audio indication of correct sequence.
Martindale PSI4000 provides a correct indication for a clockwise sequence as used in the building facilities industry.
Bright LEDs show the direction of sequence plus whether each line conductor has a voltage between 75 and 1000 Volts AC, at 45 to 65 Hz. There is also a button to activate enhanced LED brightness! The increased safety design of this phase rotation tester allows for use on both insulated and non-insulated conductors with a buzzer and bright LEDs giving a clear indication of phase rotation. Green LEDs indicate correct rotation while Red LEDs indicate incorrect rotation.
