摘要: The paper presents the method for determination of ground fault current distribution in cases when feeding cable lines are passing through urban and/or suburban areas, or many relevant data uncertain, completely unknown. problem appears as a consequence fact that surrounding installations situated under surface and cannot be visually determined verified. On basis on site measurements, developed enables compensation all deficiencies about metal involved with fluctuating magnet field appearing along around power line during an unbalanced fault. presented analytical procedure is based certain measurable quantities cumulatively involve inductive effects all, known unknown installations. performed quantitative analysis points at significance taking into account existence
