51 – How much power do I lose because of harmonics? Do I pay for harmonics on my power bill?
8:33
To tackle answering the common question “Do harmonics impact my power bill?”, we start by reviewing the different components of power and the power triangle including real power (watts or kW), reactive power (kVARS) and apparent power (kVA). Using the power triangle, with a modified 3D version incorporating harmonics, we demonstrate how harmonics impact your power system, specifically affecting the kVA total. Discover why utilities primarily bill based on kilowatts and power factor, not harmonics and learn about the indirect effects harmonics can have on power loses in your system. 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. Harmonic current can cause excess heating of transformers and cables, damaging electrical equipment. Harmonics can also cause voltage distortion, often resulting in the mis operation of equipment during critical applications. Monitoring 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 presented by Dan Carnovale can help individuals from varying background and experience levels understand what harmonics are and explore varying 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.
