This could be referred to as a “ sine wave quality factor ” as it is a measure of the amount of distortion at that given time, for that given magnitude of current. It can be measured with a simple harmonic current metering device.

WebApr 1, 2008 · These values, or harmonic indices, serve as a useful metric of system performance. The two most frequently used are total harmonic distortion (THD) and total demand distortion (TDD). ... They are measures of the effective value of a waveform and can be applied to both current and voltage. THD. According to the book “Electrical … Total harmonic distortion, or THD is a common measurement of the level of harmonic distortion present in power systems. THD can be related to either current harmonics or voltage harmonics, and it is defined as the ratio of the RMS value of all harmonics to the RMS value of the fundamental component times 100%; the DC component is neglected. where Vk is the RMS voltage of the kth harmonic, Ik is the RMS current of the kth harmonic, an…

Harmonic content makes it harder to magnetize the copper and iron in the motor’s stator and rotor, causing higher eddy current and hysteresis losses. If harmonic frequencies exceed 300 Hertz, the skin effect compounds these losses. Second, all these extra losses manifest as additional heat. find file path python
