Description
The Omicron CPOL Polarity Checker checks a series of terminals for correct wiring (replacement for battery checking method). In conjunction with a CMC test set the signal can be injected into the primary side of a CT. Thus, the correct polarity of CT wiring can be included in the test. A special continuous test signal (voltage or current) is injected at one point with the CMC, then the polarity at all terminals can be checked with CPOL. Following this procedure provides a clear indication as to whether the polarity is OK (green LED) or not OK (red LED). This procedure is much faster than the conventional method and can easily be performed by a single person. CPOL works with the polarity checker software which is part of the Test Universe Software and the Wiring Check tool of CMControlP.
