Phase Reversal

The Phase Reversal function detects incorrect phase sequence in a three-phase system, causing a connected three-phase motor or other rotating equipment to run in the opposite direction than expected.

If enabled, this protection function triggers a Phase Reversal trip if the detected current phase sequence does not match the Current Phase Sequence setting over a time period of 100 ms.

No alarm is associated with this function. The 100 ms time period is not adjustable.
