Martindale simplifies phase rotation measurement

Posted on Friday 1 January 2010

When it comes to verifying the phase sequence, or rotation, of three phase circuits, leading test equipment specialists Martindale Electric offers a professional range of testers.

Getting the phase sequence wrong can have devastating consequences for plant and machinery with serious implications for machine safety.

Providing enhanced user safety, Martindale Electric’s PSI4000 and PSI4300 non-contact phase sequence indicators can quickly and accurately identify three phase sequences for motor installations and other systems. Designed for use on both insulated and non-insulated conductors, the PSI4000 and PSI4300 carry out measurements via inductive crocodile clips, which can be simply clipped on to speed up testing and reduce the risk of coming into contact with live parts.

Another solution is the PC15250 phase rotation indicator, which has been specifically designed to quickly and simply prove the presence of all three live phases (or identify which are faulty) and show the sequence of phase rotation when all three phases are confirmed as present.
