Ground Fault DetectionGround Fault Detection_02

Check out this case study in which a PMI Revolution was used to identify ground fault disturbance.


Using the Revolution in tandem with Flex CTs effectively identified the the source of a main breaker trip.


The Revolution was set at a high enough resolution to compare captured events to time stamps from the distributed control system, however the resolution was low enough to facilitate long-term recording.


After several days of monitoring, several ground faults were identified and attributed to a faulty handling system motor.
