Method for estimation of location of the asymmetrical phase‐to‐ground faults existing during an overhead line energisation

Mathematical modelling of the voltage transfer functions of an unloaded overhead line during its energisation under faulty conditions

“…As it was mentioned in Section 1, this paper uses mathematical modelling given in [24] as a base in deriving of the TFs. To that end, the whole analysis approach given in Section 3 of [24] is retained here. In order to avoid overlapping of the papers only the newly added findings and equations will be presented here.…”

“…The papers are generally focused on either line energisation and the effects of the process [11][12][13][14] or faults and their classification and location on lines [15][16][17][18][19][20][21][22]. The authors of this paper have contributed to the field through research whose main results are published in [23,24].…”

“…The method for estimation of the location of the asymmetrical phase-to-ground faults which exist during an overhead line energisation is given in [24]. The proposed method is simple to use and it relies on knowing the fundamental system parameters and frequency estimation of the measured voltage signals.…”

“…The improved version of the mathematical modelling approach given in [24] is applied in this paper aimed at obtaining of the TFs. The improvement assumes taking into account the φ.…”

Research and application of the FETD method for the EM transient response of MTLs excited by HEMP

“…Multiconductor transmission lines (MTLs) are widely used in electrical and electronic engineering as the significant transmission path of energy and information [1][2][3][4], but they are vulnerable to external electromagnetic (EM) interferences [5], i.e. emissions from lighting EM pulse [6][7][8], high-power radars, high-altitude EM pulse (HEMP) etc.…”
