    Дослідження перенапруг під час дугових замикань на землю в електромережах 35 кВ
    (Видавництво Львівської політехніки, 2013) Яцейко, Андрій; Горошко, Олег
    In this article it is researched the influence of grounding conditions of neutral of electrical network 35 kV on the level of arc overvoltage due to the theory by: Petersen, Peters - Slep'yan and Belyakov – Dzhuvarly. There were given schematic dependencies of arc overvoltage multiplicities which depend on neutral grounding, given main schematic dependencies of combustion of grounding arc. It is shown that values of arc overvoltages significantly increased with increasing of the value of the capacitive current in the electrical network. Combined condition of neutral grounding reduces the level of arc overvoltages the best. Multiplicity does not exceed 2.4 for all theories for various values of capacitive current.
