SSC SSC JE Electrical 2025 Mock Test Series (Paper 1 & Paper 2) Electrical and Electronics Measurements Measurement of Power Measurement of Poly Phase Power
Power in a three-phase star connected balanced inductive load is measure by two wattmeter method. The phase voltage and phase current are 200 V and 10 A, respectively. The power-factor of load is 0.5. The readings P1 and P2 of the two wattmeter’s are
1
P1 = 3 kW, P2 = 6 kW
2
P1 = 0 kW, P2 = 6 kW
3
P1 = 2 kW, P2 = 6 kW
4
P1 = 0 kW, P2 = 3 kW
