Explain two wattmeter method for measurement of power in 3 phas... | Filo

SOLVED: The two-wattmeter method is applied to a three-phase three-wire 120 V system, with the meters connected to lines R and B. WR = 820 W and WB = -480 W. Find the impedance of the balanced delta connected load.A three-phase induction motor develops 20 kW when running at 90% efficiency, at a power factor of 0.45 lagging. Calculate the readings on each of the two watt meters connected to read the input power.A load of 2,500 kVA at 11 kV and a power factor of 0.8 lagging is supplied by a three-
