When it comes to verifying the phase sequence, or rotation, of three phase circuits, Martindale Electric, leaders in voltage detectors and safe isolation, offers more than one solution, with its professional range of testers.
Getting the phase sequence wrong can have devastating consequences for plant and machinery with serious implications for machine safety. From motors running backwards through to cooling or lubricating systems underperforming, one wrong connection can lead to a major maintenance headache.
Providing enhanced user safety, the unique PSI4000 and PSI4300 non contact phase sequence indicators from Martindale Electric 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 from Martindale 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.
LEDS provide a clear indication of phase rotation and have a high intensity setting for when working in strong ambient light. Similar in function, the only difference between the two phase sequence indicators is that the PSI4000 provides a correct indication for clockwise sequence, as used in the building facilities industry, while the PSI4300 provides a correct indication for anticlockwise sequence as used, for example, in power utilities.
Another solution from Martindale Electric 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.
Easy to operate, the PC15250 provides a fast, effective battery free method of identifying unmarked cables and ensures that 3-phase outlets and machines are wired correctly.
For a choice between long exposed tips for reaching difficult to access contacts and shorter tips for increased safety, the PC15250 also features retractable GS38 shrouds and comes supplied with integral fused leads, crocodile clip and high quality test probes which conform to GS38.
In addition to a dedicated range of phase sequence indicators, Martindale Electric also supply a range of tools such as the VT28 Voltage Indicator and the ET4000 and ET45000 17th Edition multi-function testers, which can be used to provide phase sequence indication in addition to their main functions.
