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°

WebMar 19, 2024 · Most likely, you will have access to a wattmeter for measuring true power, whose reading you can compare against a calculation of apparent power (from multiplying total voltage and total current measurements). ... Wattmeter reads true power; product of voltmeter and ammeter readings yields apparent power. How to Calculate the Apparent … WebMar 30, 2024 · The reading of wattmeter will be, Average power = V pc I cc cos ϕ Where, V pc is the voltage across pressure coil I cc is current flows through the current coil ϕ is the phase angle between V pc and Icc So, wattmeter is a device capable of detecting voltage, current and the angle between the voltage and the current to provide power readings. lighthouse vokabeltrainer app
