Section Location Technology Based on Minkowski Distance of Three-phase Asymmetric Current Components [PDF]
E3S Web of Conferences, 2021 Fault components in the fault path and the non-fault path differ due to the unbalanced distribution of positive, negative and zero-sequence components in the line in the case of a single-phase earth fault in the power distribution network.

Generalized Fault-Location Scheme for All-Parallel AT Electric Railway System
Energies, 2020 The existing fault location methods for all-parallel autotransformer railway systems (AARS) have limitations because they are generally designed for several given feeding conditions. In alternate feeding conditions, the existing fault location methods do

An Effective EMTR-Based High-Impedance Fault Location Method for Transmission Lines
, 2020 This paper summarizes the electromagnetic time reversal (EMTR) technique for fault location, and further numerically validates its effectiveness when the fault impedance is negligible. In addition, a specific EMTR model considering the fault impedance is
