Design and Analysis of Single-Tuned Passive Filters for Total Harmonic Distortion (THD) Mitigation and Power Quality Enhancement

Journal of Engineering and Sciences
Harmonic distortion caused by nonlinear loads is a significant challenge in power systems, often resulting in reduced efficiency, overheating, and equipment malfunction. Despite the availability of various mitigation techniques, many fail to offer a cost-effective and practical solution for distribution networks.

Pengukuran Total Harmonic Distortion (THD) Tegangan dan Arus di Lingkungan MATLAB

Jurnal Manajemen Informatika & Teknologi
The daily operational landscape is fundamentally dependent on electrical energy, with the nature of the electrical loads frequently exhibiting varied profiles. A notable aspect of diminished power quality is harmonic distortion, which is characterized by disturbances in the electrical waveforms of both current and voltage.

Analisis Penggunaan Filter Damped untuk Mereduksi Total Harmonic Distortion (THD) di Rumah Sakit Umum Daerah (RSUD) Klungkung

Majalah Ilmiah Teknologi Elektro, 2018
Pengoperasian beban non linier merupakan penyebab timbulnya harmonisa. Tingkat distorsi atau disebut Total Harmonic Distortion (THD) yang tinggi berpotensi menurunkan kualitas energi listrik yang disalurkan. Dalam penelitian ini dilakukan pengukuran THD pada tiap Sub Distribution Panel (SDP) di RSUD Klungkung.
