What is the difference between harmonics and transients? Harmonics and transients can both create distortion on the sinewave. They are both a cause of deviation of the sinewave from its actual form. However, the basic difference between harmonics and transients is that harmonics tend to stay more in a system. Transients are hugely repetitive and are nanosecond occurrences. Whereas transients are created by inductive load switching, harmonics are created specifically by non-linear loads. How do you know if you have a Harmonics issue? It’s easy to assume you have a harmonics issue. However, hav...
