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.
