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”

Non-Standard Solutions for Supports of High Voltage Overhead Lines in the Aspect of Landscape Protection and Electromagnetic Field Impact

Published by Marek JAWORSKI, Politechnika Wrocławska, Katedra EnergoelektrykiORCID. 0000-0002-6537-050X Abstract. The article presents issues related to choosing an overhead line route in the aspect of landscape protection. The possibility of using nonstandard supports, which task is to replace traditional electricity pylon and better integration into the surrounding landscape, was pointed out. The paper describes theContinue reading “Non-Standard Solutions for Supports of High Voltage Overhead Lines in the Aspect of Landscape Protection and Electromagnetic Field Impact”

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”

Energy Generation Through Wind Power Systems

Published by Alex Roderick, EE Power – Technical Articles: Energy Generation Through Wind Power Systems, August 21, 2021. Because winds are primarily caused by uneven heating effects of the sun, wind energy is considered to be an indirect form of solar energy and is therefore renewable. The primary cause of winds is the uneven heating ofContinue reading “Energy Generation Through Wind Power Systems”
