Fault Detection and Classification in EHV Transmission Line Based on Wavelet Singular Entropy
TL;DR: In this paper, a novel fault detection and classification technique called wavelet singular entropy (WSE) is proposed for extremely high-voltage transmission line using the fault transients, which incorporates the advantages of the wavelet transform, singular value decomposition, and Shannon entropy.

Voltage-Sag-Profiles-Based Fault Location in High-Speed Railway Distribution System
TL;DR: In this article, the authors proposed a novel fault location strategy for high-speed railway distribution system by measured voltage data of existing box-type substations, which makes use of the difference between the calculated voltage and measured voltage at the end of the lines to locate the fault.
