“…The detection of these defects and their isolation prevent equipment damage, therefore reducing the costs of grid operation. Single line-to-ground faults are the most common type of fault in medium voltage electric networks and their effects on consumers depend on the neutral grounding method of the network [7][8][9][10]. Furthermore, in medium voltage networks where overhead lines are predominant, single phase-to-ground faults account for more than 80% of the total number of faults [11,12].…”

“…In works [13][14][15][16][17][18] are presented different methods for detecting line-to-ground faults that occur in medium voltage electrical networks. In the case of faults with very high fault resistance, the method of controlling the effective value of the current through the neutral grounding resistor of the medium voltage network is more efficient [3,4,7,10,19,20].…”

One important problem in the operation of medium voltage networks is the detection of a single-line-to-ground fault in its incipient state, when the fault resistance values are very high. In a medium voltage (MV) distribution network with a neutral grounding resistor (NGR), one of the methods employed to discriminate a single line-to-ground fault is the use of an overcurrent relay with an operating characteristic adjusted according to the effective value of the current flowing through the limiting resistor. In case of a single line-to-ground fault with a high fault resistance value, the correct tripping settings of the protective relay require the precise computation of this current. In comparison to the assumptions made by the models from the literature—the three-phase voltage system of the medium voltage busbars is symmetrical and there are no active power losses in the network insulation—the model proposed in this paper considers the pre-fault zero-sequence voltage of the medium voltage busbars and the active power losses in the network insulation, which is necessary in certain fault conditions where the use of the former leads to unacceptable errors.

“…In [5], authors employed WT as a fault classifier for the classification of faults in a 400-kV, 300-km-long two-terminal transmission line. In [6,8,9], authors applied WT for detecting faults on TLs. In [7], WHT has been introduced for the protection of SCCTL.…”
