Abstract :
The new instantaneous phasor method originated by the author is applied for the evaluation of efficiency of induction motors installed in the field. The unique property of the instantaneous phasor method is that the phasors of one phase can be used to represent all three phases. The active power components that include the fundamental-frequency, positive-sequence, negative-sequence, and the harmonic power components are studied in this paper.
