ABSTRACT:
A method and apparatus for determining the total harmonic distortion and the power factor of a non-linear load circuit coupled to an a.c. power source generating a.c. current and a.c. voltage, the a.c. current input to the load circuit being in phase with the a.c. voltage provided across the load circuit by the a.c. power source. The invention measures the total harmonic distortion of a.c. current and a.c. voltage at the non-linear load circuit and calculates the total harmonic distortion and the power factor as a function of both.
