Substation Grounding Basics: Step, Touch, and Transferred Voltages

Published by Lorenzo Mari, EE Power – Technical Articles: Substation Grounding Basics: Step, Touch, and Transferred Voltages, October 09, 2020. Learn about Earth potential gradients and shock situations in substations. The conduction of high currents to ground in substations due to atmospheric disturbances or equipment failures generates potential gradients on Earth’s surface that are a threatContinue reading “Substation Grounding Basics: Step, Touch, and Transferred Voltages”

6 Techniques for Controlling Harmonic Distortion

Published by Simon Mugo, EE Power – Technical Articles: 6 Techniques for Controlling Harmonic Distortion, May 15, 2023. Harmonics–currents or voltages at a multiple of the power systems’ fundamental frequencies– originate from non-linear loads in power systems. This article will introduce six techniques necessary to reduce harmonic distortion. The earliest method of controlling problems associated withContinue reading “6 Techniques for Controlling Harmonic Distortion”

Combining Waveforms in a Power System to Cancel Harmonic Components

Published by Alex Roderick, EE Power – Technical Articles: Combining Waveforms in a Power System to Cancel Harmonic Components, August 23, 2021. Harmonics can cause transformers to fail, motors to burn out, circuit breakers to trip (nuisance tripping), and neutral conductors and other parts of a power distribution system to overheat. Severe overheating leads to electricalContinue reading “Combining Waveforms in a Power System to Cancel Harmonic Components”
