WebMar 30, 2024 · High THD can cause heating and dielectric breakdown. Heating in rotating machines: Harmonic distortion causes additional copper and iron losses in the stator and in the rotor. The losses are due to differences in the speed of the rotor and the harmonics-inducing rotating fields. WebJun 8, 2024 · Total harmonic distortion (THD) is the ratio of the sum of the powers (RMS amplitude) of all the harmonics to the power (RMS amplitude) of the fundamental frequency. Inharmonic distortion differs from harmonic distortion by being an overtone that is not an integer multiple of the fundamental frequency.
