      With a neat circuit and phasor diagram explain the three phase power measurement by two wattmeter method. Now, the sum of two Wattmeter readings will be given as. The above equation (1) gives the total power absorbed by a 3 phase balanced load. Thus, the sum of the readings of the two Wattmeters is equal to the power absorbed in a 3 phase ...

      A motor with four leads is a two-phase bipolar motor. We measure the resistances between pairs of wires to determine which wires belong to the same winding. A motor with six leads is either a two-phase unipolar motor or a three-phase bipolar motor. We can determine the specific type by measuring the resistances between pairs of wires.
