Effects of Harmonics on Resistive Loads
As a continuation of my article on effects of harmonics on electrical equipment, let us provide an example of the effects of harmonic currents on 1-ohm resistive load drawing 1 …
Phase Shifting Transformers to Cancel Harmonics
When there are several non-linear loads of equal ratings in a power systems, the use of phase shifting transformers could help cancel harmonics. After harmonic filters, phase shifting transformers are …
Phase Sequence of Harmonics
In the article Effects of harmonics on Electrical Equipment, harmonics distort the fundamental frequency of the mains voltage waveform which affects the performance of other electrical equipment and creates additional …
