Experimental investigations of switching overvoltages in 110 kV network of power system of Montenegro

A part of comprehensive experimental investigations of switching overvoltages in the segment of 110 kV transmission network of the electric power system (PS) of Montenegro is given, analyzed and discussed. The performed experimental investigations are the first investigations of such kind of problems ever performed in the transmission network of PS of Montenegro. A number of obtained very valuable data allows complex and sensitive analysis not only about the characteristics of the possible switching overvoltages which can appear during the period of exploitation, but also about their influences on the observed lines and their elements, as well as on the segment of the observed transmission network. The measured data could be also used for the risk assessment and analysis of the electric breakdown of the insulation of lines, as well as for the drawing the recommendations and conclusions about future exploitation and possible improvements of the particular components and the entire observed system.
