The two-wattmeter method gives P1 = 1200 W and P2 = 400 W for a three-phase motor
Chapter 12, Problem 12.70(choose chapter or problem)
The two-wattmeter method gives P1 = 1200 W and P2 = 400 W for a three-phase motor running on a 240-V line. Assume that the motor load is wye- connected and that it draws a line current of 6 A. Calculate the pf of the motor and its phase impedance.
