67 - When do you need a harmonics study?

4:46

• Harmonic Studies: Not all situations with harmonics require a full study. If you add significant harmonic loads or power factor correction capacitors, you should consider modeling the power system harmonics. • Harmonic Filters: When significant harmonics are present on a power system, consider using harmonic filters over straight capacitors when harmonic distortion exceeds certain thresholds, to prevent amplifying harmonics. • Harmonic Load and Analysis: If your harmonic loads on the power system, exceed 15% of transformer kVA, consider harmonic resonance checks and possibly full harmonic analysis to prevent damage to the power system. • Power Factor Correction: When applying power factor correction, it's crucial to understand which harmonics are present and their flow to avoid creating resonance that could damage the power system. 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.
