“…Two voltage unbalance conditions are monitored for the HIF (broken conductor) identification; however the characteristic quantity cannot be computed directly from the phase voltages. Earlier works have considered either positive sequence voltage drop or the percentage of negative and zero sequence voltage drops [18,19]. In this paper, the HIF detection has been done using both the quantities, the positive sequence voltage drop and the percentage of negative and zero sequence component voltage along with improved threshold values.…”

“…The relative differential voltage has the advantage of remaining constant after the faulted point, even if the positive impedance of the source is not so small compared to the impedance of the loads [18]. Hence this quantity gives a good indication of the occurrence of the HIF.…”

“…Garcia-Santander et al [18] proposed a positive sequence voltage drop based HIF detection method, where the analysis is carried out for different high resistance values as well as for different grounding conditions of the substation transformer. Senger et al [19] described the HIF detection based on negative and zero sequence voltage components.…”

High-impedance faults (HIFs) on distribution feeders cannot be detected by conventional protection schemes, as HIFs are characterized by their low fault current level and waveform distortion due to the nonlinearity of the ground return path. This paper proposes a method to identify the HIFs in distribution system and isolate the faulty section, to reduce downtime. This method is based on voltage measurements along the distribution feeder and utilizes the sequence components of the voltages. Three models of high impedance faults have been considered and source side and load side breaking of the conductor have been studied in this work to capture a wide range of scenarios. The effect of neutral grounding of the source side transformer is also accounted in this study. The results show that the algorithm detects the HIFs accurately and rapidly. Thus, the faulty section can be isolated and service can be restored to the rest of the consumers.

“…For an underground cable, HIF is normally caused by insulation defects that exposes the conductor to contact with non-conducting elements. Different HIF detection schemes have been proposed in the past [1][2][3][4][5][6][7][8][9][10][11][12]. The process of HIF detection comprises two basic steps; feature extraction and pattern matching or classification.…”

“…Unlike LIF, comparatively less research studies have been conducted to identify the HIF location. There are several approaches to determine the HIF location such as network topology technique [5][6][7][36][37][38][39], travelling wave technique [40][41][42][43] and knowledgebased technique [44][45][46][47][48].…”

The article presents a new algorithm for detecting conductor breaks in ungrounded radial distribution networks. The algorithm uses the instantaneous values of the phase-to-phase voltages, measured at the end of the radial line as input signals. As the first indicator of conductor break, the broken conductor index (BCI) was introduced. BCI is a phase comparator that indirectly estimates the angle between the phase-to-phase voltages by calculating the integral of the product of the instantaneous values. As an additional indicator of conductor break, the algorithm uses a comparison of the RMS values of the phase-to-phase voltages. The proposed algorithm testing was performed on a model of the radial distribution network with multiple lines modeled in the MATLAB/Simulink software package. Experimental testing of the presented algorithm was performed on a laboratory model of the test network.
