Abstract
A method for measuring total core loss by means of a modified Hay bridge is established. It is shown from Kirchhoff´s laws that the new method is applicable when the time rate of change of flux in the core is nonsinusoidal and exhibits quarter-wave symmetry. An experimental comparison of the modified Hay bridge method and the reflecting wattmeter indicates agreement within about 2% when the waveform has said symmetry.
