Combined phase power measurements
All Classic combined phase power measurements are identical with Modern combined phase power
measurement. See 5.1.5 section Combined phase power measurements for details.
Total Vector combined power measurements
Standard compliance: IEC 61557-12 Annex A and IEEE STD 1459-2010 Section 3.2.2.6
Total Vector combined (fundamental + nonfundamental) active, nonactive and apparent power and
total power factor are calculated according to the following equation:
