摘要：

Overvoltages formed by switchings or lightning discharges in a combined high voltage (110 kV or more) electrical network with overhead lines and cables may be dangerous to insulation of the cables. Overvoltages in the aerial lines with cable insertions increase reliability of insulation of the cables. For such combined circuits, it is important to select and adjust parameters of surge arresters in the main substation and transformer substations with deep lead. The paper analyses the specific network with the deep lead and with cable internal ring. Operating conditions of different surge arresters in the combined electrical network of 110 kV with aerial and cable lines are analysed.
