In this article, I have discussed the difference between a conventional transformer and a K-factor rated transformer. In modern-day plants, Variable Speed Drives (VSD) are widely used. The project I …
What is Transformer K-Factor Rating A conventional transformer has restricted use in an environment where non-linear loads are utilized, unbalanced input voltage or load current exceeds 5% total harmonic distortion. …
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 …
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 …
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 …
An ideal power quality for a source of energy to an electrical load is represented by a pure sine wave waveform of voltage. The term pure means that it does …
