“…Fault location algorithms based on the analysis of the faultoriginated EM transients are often tested by using the results of numerical simulations carried out by means of electromagnetic transient programs (EMTP) [19] able to accurately represent the propagation phenomena that takes place in line feeders (e.g., [20], [21]). …”

Abstract-The paper presents a procedure for fault location in distribution networks, based on the use of the integrated time-frequency wavelet decompositions of the voltage transients associated with the fault-originated travelling waves. The proposed analysis of time-frequency wavelet decompositions has been found to improve the identification accuracy of the frequencies associated to the characteristic patterns of a fault location with respect to a sole frequency-domain wavelet analysis. Several laboratory fault tests, carried out by means of a reduced-scale model of a distribution feeder, are used to illustrate the characteristics and assess the performances of the proposed improved procedure. The paper also illustrates the application of the proposed procedure to a transient, originated by a permanent phase-to-phase fault, measured in a real distribution network in which a post-test analysis has identified the faulted branch.

“…No actual field implementation/testing are mentioned in the paper. [26] Summary: This paper describes a 'fault transient comparison scheme' for multi-ended distribution feeders (teed feeders). Three relays are installed at each teed feeder end, respectively, and currents at each feeder end are measured by CT's locally.…”

“…Protective relays capable of identifying disturbances correctly, reliably and fast [1][2][3][4][5] must be applied to differentiate between transient disturbances due to events such as transformer inrush, fault, load and capacitor switching. Transients due to capacitor bank switching and the related power quality problems are discussed in [6][7][8].…”

An efficient procedure for classification of transient phenomena in distribution systems is proposed in this paper. The proposed method has been applied to classify some transient phenomena such as inrush current, load switching, capacitor switching and single phase to ground fault. The new scheme is based on wavelet transform algorithm. All of the events for feature extraction and test are simulated using Electro Magnetic Transient Program (EMTP). Results show high accuracy of proposed method.
