The wattmeter reads

WebThe two-wattmeter method produces wattmeter readings P1 = 1560 W and P2 = 2100 W when connected to a delta-connected load. If the line voltage is 220 V, calculate: (a) the per-phase average power, (b) the per phase reactive power, (c) the power factor, and (d) the phase impedance. Solution: WebMar 24, 2024 · The reading of the wattmeter (W 1) is given by: W 1 = E R Y I R c o s ϕ where, ϕ = Angle between E RY and I R E RY = Line Voltage I R = Line current Drawing phasor by taking phase voltage (ER) across Z 1 as the base reference. Since the load is capacitive, therefore I R leads E R by angle ϕ. Also, line voltage ERY leads to phase voltage ER by 30°
