Estimation of Vulnerable Areas to Faults Caused by Tree Vegetation in Power Distribution Systems

IEEE Access
Faults in power distribution feeders cause damage to power utilities due to the deterioration of reliability and power quality indexes and the displacement of field maintenance teams to replace or repair power grid equipment. Additionally, consumer units

Identification and location method of asymmetric faults in coal mine power network

Gong-kuang zidonghua, 2018
Three asymmetrical faults of singe-phase grounding, singe-phase line breakage and ferroresonance in coal mine power network are easily misjudged, and existing methods hardly identify the three faults correctly.

RETRACTED: Cross‐country high impedance fault diagnosis scheme for unbalanced distribution network employing detrended cross‐correlation

IET Generation, Transmission & Distribution
Distribution networks frequently experience cross‐country failures (CCFs).This study presents research that demonstrates how Cross‐Correlation may be used to extract distinctive features from faulty current signals, hence providing a threshold‐based ...
