Abstract :
A theoretical investigation of the relative magnitudes of the phase magnetizing currents and of the wattmeter readings when measuring iron losses in a three-core transformer is given. The effect on the accuracy of the observed iron losses of phase-angle errors in the wattmeters is examined. The magnitude of possible errors is shown by numerical example.
