Insulation Piercing Connector How to identify phase line grounding with a low-voltage tester?
Low-voltage testers can also be used to identify phase line grounding: When a three-phase three-wire star-connected AC circuit is touched with a test pen, two of the roots are usually slightly brighter, while the other is darker, indicating that the darker phase line has grounding, but it is not serious. If two are very bright and the other is not bright, then this one has grounding. In a three-phase four-wire circuit, when a single-phase grounding occurs, the neutral line will light up when the test pen is used to test the neutral line.
