Modelling and Simulation of Reduce Harmonic Distortion in Non-linear Loads

by Agus Junaidi, Rahmaniar, Rudi Salman, Joni Safrin Rambey and Baharuddin

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 5, Page # 364–369, 2020; DOI: 10.25046/aj050545

Abstract:

Harmonic distortion is a problem that can be caused by the use of power electronic devices. The effect of harmonics has an impact on changes in the input voltage source waveform which is referred to as wave defects. This incident has an impact on electronic faults and overheating of the power transformer coil as a…

A Novel De-rating Practice for Distributed Photovoltaic Power (DPVP) Generation Transformers

by Bonginkosi Allen Thango, Jacobus Andries Jordaan and Agha Francis Nnachi

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 4, Page # 154–160, 2021; DOI: 10.25046/aj060418

Abstract:

Transformers are habitually designed and manufactured for operation at a fundamental frequency of 50Hz and sinusoidal load current. Transformers are susceptible to non-linear loads. The inception of switching action characterises Non-linear loads and consequently nonsinusoidal load current which brings about higher transformer service losses, hotspot temperature rise, and degradation of cellulosic and liquid insulation, and…
