5.4: Viewing Individual Phase Indication for Power Functions

The EPM 5300P normally displays a three-phase indication for PF, KW, KVAR, KVA readings. To view the individual phase A, B and C for those power functions follow the procedure below. This procedure is particularly useful for detecting a current transformer (CT) polarity reversal. A CT polarity reversal will result in a low or negative KW indication, while the KVA will be unaffected.

Step 1:

a. Press POWER to select power readings. Press PHASE/NEXT to select a specific power function (PF, KW, KVAR, KVA).

Step 2:

Press and hold the POWER button to scroll through the instantaneous single-phase power readings.
