Analysis of the Impact of Reduction 400 kV Overhead Transmission Line Dimensions on the Transient Overvoltages



The paper presents solutions of the problem in reducing the transmission line configuration (geometry) in terms of transient overvoltages jeopardy in accordance with the EN 50341-1 electrical line design and IEC 60071-1 insulation co-ordination standards. Here below the implemented statistical methods and the obtained results of the comparison of a classical 400 kV electrical line in paired version with a compact version in terms of switching and lightning overvoltages as well as electromagnetic radiation and noise are presented.
