Electrical harmonic distortion

WebHarmonic distortion can have detrimental effects on electrical equipment. Unwanted distortion can increase the current in power systems which results in higher … WebHarmonics have frequencies that are integer multiples of the waveform’s fundamental frequency. For example, given a 60Hz fundamental waveform, the 2nd, 3rd, 4th and 5th harmonic components will be at 120Hz, 180Hz, 240Hz and 300Hz respectively. Thus, harmonic distortion is the degree to which a waveform deviates from its pure sinusoidal

WebJan 24, 2014 · Compatibility levels: Equipment is designed to tolerate / be immune to harmonic distortion up to some level, the compatibility level. If we can keep the power system harmonic levels below the compatibility levels, the equipment will work. (The compatibility levels are defined in IEC 61000.2.2 and IEC 61000.2.12.) WebThe control unit calculates the total harmonic current distortion THD-R up to the fifteenth harmonic using the following equation: The current THD-R cannot be higher than 100%. Use the total harmonic distortion THD-R (I) to assess the distortion of the current wave with a single number. The following table shows the THD-R limit values.
