Do you connect a harmonic filter to ground? No. And in this video learn more about the nature of harmonic currents and why the design and application of harmonic filters require a different approach with a three-phase system compared to what you may be accustomed to seeing with other solutions like surge protection that do require the device to have a connected path to ground. Harmonic FAQ Series What are harmonics and where do harmonics come from? Harmonics are generated from non-linear loads that typically include power electronics such as variable frequency drives (VFD) and LED lights. Current harmonics cause excess heating of transformers and cables, and damage electrical equipment. Harmonics can also cause voltage distortion, often resulting in the mis operation of equipment during critical applications. Calculating harmonics and measuring harmonics are critical steps in selecting the best harmonic solution to reduce the total harmonic distortion or THD on a power system to comply with the IEEE-519 standard. Power factor correction and harmonic resonance should also be considered. Eaton’s Harmonic Frequently Asked Question’s FAQs collection of videos hosted by Dan Carnovale can help individuals from all different levels of education understand what harmonics are and explain many different solutions for mitigating harmonics on an electrical power system. Dan Carnovale P.E. has decades of experience in power quality and harmonics and is a recognized electrical industry expert in power quality and power systems. He is the creator and director of Eaton’s Power Systems Experience Centers (PSEC) in Pittsburgh PA and Houston TX. The PSECs provide visitors with live demonstrations of hands-on power quality and harmonic situations and solutions that can be seen first-hand in the Power Quality Lab.
