FIELD: measuring equipment.
SUBSTANCE: momentary values of currents of two phase are measured and momentary values of voltages between these phases and third phase are measured as well. These values are multiplied and momentary powers are produced. Then variable components of these multiplication results are picked, and integrated from the time of transfer of inter-phase voltages over zero during given time span.
EFFECT: broader functional capabilities.
