59 - If my harmonic distortion on my neutral exceeds 100%, should I be concerned?

• Harmonic Distortion Concerns: We discuss the concerns and the importance of understanding the implications of excessive neutral harmonic current and its potential impact on the system. • Understanding Harmonic Distortion: We explore the concept of triplin harmonics adding up on the neutral and how different harmonics, particularly the third harmonic, can lead to significant neutral current, potentially resulting in excessive percent distortion. • Calculating Total Harmonic Distortion (THD): We illustrate the calculation of THD, showing how all harmonics added together, divided by the fundamental, can lead to a high percentage of distortion on the neutral, potentially reaching 1000% particularly when the fundamental current is low. • Neutral Current Rating and Harmonic Distortion: We conclude that having more than 100% distortion on the neutral is not a concern unless the rms current exceeds the rating of the neutral. 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 live demonstrations of hands-on power quality and harmonic situations and solutions can be seen first-hand in the Power Quality Lab.
