Lightning Protection of Substations with Cable Inserts,
Abstract
At the present time, cable inserts are widely used at hydroelectric power plants for connecting transformers to collecting bars. The capacitance of the cable promotes a reduction in overvoltages in the substation and with a definite cable length, subsequently called 'safe,' the possibility arises of simplifying the lightning protection of a substation which does not have lightning arresters at the cable coupler terminals. The present work is devoted to determing the 'safe' length of cable inserts for 110-220 kV substations.
