DWT‐based extraction of residual currents throughout unearthed MV networks for detecting high‐impedance faults due to leaning trees | | Modelling of a high-impedance arcing fault due to a leaning tree in medium voltage (MV) networks was experimentally verified and the network transients due to this fault were also investigated. Even though the tree had a very high resistanc |
DWT-based investigation of phase currents for detecting high impedance faults due to leaning trees in unearthed MV networks | | In this paper, features of earth faults due to leaning trees are extracted from the network phase currents using the discrete wavelet transform (DWT). Due to the associated arc reignitions, the initial transients in the electrical network g |
Feature Extraction of High impedance arcing Faults in Compensated MV Networks. Part I: DWT-Based Analysis of Phase Quantities | | In this paper, the initial transients in the electrical network due to arc reignitions

Modeling and experimental verification of a high impedance arcing fault in MV networks | | -In this paper, a high impedance arcing fault of the tree leaning type in medium
voltage (MV) networks is modeled and experimentally verified. The fault is represented as
two parts; an arc model and a high resistance. The arc is generat |
Verification of DWT-based detection of high impedance faults in MV networks | | Abstract The faults due to leaning trees are common in Nordic Distribution networks. In [1],
the detection of this fault type has been discussed and the faulty section has been estimated
using a novel selectivity technique. This detecti |
DWT-BASED DETECTION OF HIGH IMPEDANCE FAULT DUE TO LEANING TREES IN COMPENSATED MV NETWORKS | | ABSTRACT Features of faults due to leaning trees are extracted using discrete wavelet
transform (DWT) and an absolute sum of the detail coefficient d3 over a period of power
frequency cycle is used as a detector. DWT is processed on the |
Operation evaluation of DWT-based earth fault detection in unearthed MV networks | | A novel selectivity technique to estimate the faulty feeder in MV networks was
introduced in [1]. This technique depended on the directionality of Discrete Wavelet

Arcing fault identification using combined Gabor Transform-neural network for transmission lines | | Abstract This paper presents an intelligent identification scheme for transient faults in
transmission systems using Gabor Transform (GT) and Artificial Neural Network (ANN). The

Modified setting of overcurrent protection for distribution feeders with distributed generation | | Connecting Distributed Generators (DGs) into conventional distribution systems
leads the protection design assumptions to become incorrect. These generators are
commonly utilized with renewable energy resources including solar photovolt |
