Why do non-linear loads have low power factors and why is it important to have a high power factor?

Published by Mirus International Inc., [2010-01-08] MIRUS-FAQ001-B2, FAQ’s Harmonic Mitigating Transformers, 31 Sun Pac Blvd., Brampton, Ontario, Canada. L6S 5P6. Power factor is a measure of how effectively a specific load consumes electricity to produce work. The higher the power factor, the more work produced for a given voltage and current. Figure 3-1 shows theContinue reading “Why do non-linear loads have low power factors and why is it important to have a high power factor?”

PQ Analysis: Power Factor, Unbalance and Harmonics

Published by testguy, November 23, 2019. Website: testguy.net Power Factor, Unbalance and Harmonics Electrical loads are often composed of more than just pure resistance, the combination of resistance and reactance in an AC system is called the impedance. Reactance comes in two forms: inductive and capacitive, both of which do not contribute to “useful” work on theContinue reading “PQ Analysis: Power Factor, Unbalance and Harmonics”

The Need for Harmonic Modeling and Mitigation in Generator Applications: A Conversation and Guide

White Paper 08-03-2021 Published by Michael McGraw, USA National Sales Manager, Mirus International Inc., Introduction & Structure It is widely accepted that performing harmonic studies for non-linear applications is important to ensure a workable and energy efficient installation. It is also accepted that these harmonic studies be performed under normal source conditions and maximum operatingContinue reading “The Need for Harmonic Modeling and Mitigation in Generator Applications: A Conversation and Guide”
