High impedance Fault Detection in Low Voltage Overhead Distribution based Wavelet and Harmonic Indices

Published by Enaam ALBANNA1, Alya H. AL-RIFAIE2, Ahmed A. Abdullah AL-KARAKCHI3, Northern Technical University (1,2,3) ORCID: 1. 0000-0002-3974-0116; 2. 0000-0002-7978-2193; 3. 0000-0003-1151-3015; Abstract. High-impedance fault HIF occurs when an energized conductor makes contact with a surface with a high impedance. Conventional overcurrent protection cannot detect this fault due to the low fault current, and thereContinue reading “High impedance Fault Detection in Low Voltage Overhead Distribution based Wavelet and Harmonic Indices”
