“…The same performance was also expected, if an arcing is accompanied into the fault path. Actually, those protection functions depending on travelling waves are usually less sensitive to non‐linear arcing elements as concluded in [34].…”

This study presents an earth fault distance determination algorithm for distribution networks using active travelling waves. Three triacs are used in parallel with a three-phase breaker poles to overcome the mechanical inequality of the poles' reclosing times, so that the three phases are simultaneously reclosed. As the proposed fault location technique is an active type with controllable reclosing instant, the arrival time of the reflected surge from the fault point should be stamped precisely. For this purpose, three different travellingwave detection algorithms are evaluated including the discrete wavelet transform, Hilbert transform, and signal derivative. The fault location performance is evaluated under different fault conditions such as fault distances, fault resistances, and busbar faults. Due to utilising the reclosing transients, the proposed fault location function successfully estimates the fault distance for different earthing concepts such as unearthed, compensated, and earthed networks. This study is accomplished via simulating a typical 20 kV distribution network by the ATP/EMTP program. The results ensure the superior performance of the proposed fault distance estimation algorithm for earth faults in distribution networks.

“…However, as the resistance increases, very little current will flow to ground at the fault location and for a grounding resistance of 1 Ω, almost no current flows and the fault loop impedance is almost equal to that of a core to sheath fault only. In real life, a time varying fault resistance is expected [6,88]. For fault location problems, this can be a potential problem, as a very high accuracy is needed for exact fault location.…”

University in partial fulfilment of the requirements for the PhD degree in Electrical Engineering. The research has been carried out between the 1.09.2010 and the 15.07.2013 at the Department of Energy Technology for Energinet.dk by which I was hired as a PhD-student for the entire project period.The project has been followed full time by two supervisors: Professor Claus Leth Bak (Department of Energy Technology) and Dr. Unnur Stella Gudmundsdottir (Energinet.dk).Energinet.dk has fully funded the research leading to this thesis "Online Location of Faults on AC Cables in Underground Transmission Systems". This funding has been vital for this research project. Travelling to conferences, two visits at forging research institutions, renting of laboratory equipment and performance of and field measurements was made possible thanks to support from the company. During the projet period I supervised two master projects and thought one semester course in power system transients.The scientific papers written as a part of this PhD are included in the back of both the printed version of the thesis as well as in the PDF-file. The papers should not be considered a part of this monograph, but are enclosed if the reader is interested.This thesis has five parts and appendices. An overall literature reference list is presented at the end of the main report. A list of the authored publications is presented at the end of the thesis. Literature references are shown as [i], where i is the number of the literature in the reference list. Tables, figures and equations are shown as C.F, where C is the chapter number and F is a unique number for the figure or table. AcknowledgementsI owe gratitude to many people who helped me in different ways. I would like to thank:• My supervisors, Claus Leth Bak and Unnur Stella Gudmundsdottir for all their help, comments, and many technical discussions during the last three years.• Carl-Erik Madsen, Henrik Kastberg and Carl Willi Hansen for their help with carrying out the field measurements.

“…In order to improve the power reliability, a variety of protection devices are developed such as fault locator which is proposed in literatures. Accurate fault location reduces time and costs related to the dispatched crews searching to find the fault location [17]. Also, provides customers and consumers feeding with minimal interruption and improves the performance of the power system [18].…”

In this technique the relay can detect the fault and can discriminate between internal and external fault without the need for communication links. That combines of both impedance based methods and traveling wave based methods has been developed and presented in this paper. The proposed method first determines whether the fault is backward or forward to the measured relay and then determines if the fault is grounded or ungrounded. Next, the impedance based method is used to identify the fault for ungrounded faulted. Finally the traveling wave method is used to detect the fault for grounded fault by using the ground and Ariel mode. The simulation results indicate a good accuracy and more security of the suggested protection scheme compared with others schemes with different types of faults, fault resistances and fault inception angles using MATLAB/SIMLINK simulation.
