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”

Understanding Current and Voltage Harmonics

Published by L&T Electrical & Automation, Website: lntebg.in Source: https://www.lntebg.in/about-us/blog/understanding-current-voltage-harmonics/ Current and voltage harmonics are often used interchangeably. At most places, only harmonics is quoted and whether the values pertain to current or voltage is not mentioned. The differentiation can be done on the basis of their origin. Understanding Total Harmonic Distortion The current andContinue reading “Understanding Current and Voltage Harmonics”
