What is THD or Total Harmonic Distortion?
Harmonic distortion is the production of harmonic (unwanted) frequencies by an electronic system when a signal is applied at the input. To make matters worse, harmonics can sometimes be transmitted from one facility back through the utility’s equipment to neighboring businesses, especially if they share a common transformer. This means harmonics generated in your facility can stress utility equipment or cause problems in your neighbor’s facility and vice versa.
