GS&EI ElectEngg 14 2024 1601-2025 In the two-wattmeter method, the total power is the sum of the readings of the two wattmeters. The individual wattmeter readings depend on the phase angle between the voltage and current. Equal positive readings imply that both wattmeters are measuring positive power, and their sum represents the total power at unity power factor.
If the readings of two wattmeters are equal and positive in the two-wattmeter method, the load power factor in a balanced 3-phase, 3-wire circuit will be
