Harmonic distortion is a type of pollution to the electricity supply that is caused by non-linear loads. Some levels of harmonics on the network are acceptable. But as harmonic levels increase, so too does the likelihood of problems occurring. These problems often require costly maintenance to fix and can even lead to plant downtime.
In this video, Luke Archer, a drive system engineer for MKE Engineering Group, outlines the causes and symptoms of harmonic distortion and highlights some of the technology that is available to help ensure harmonics levels are kept well within legal limits.
