Lightning Overvoltage Analysis and Model Establishment of XLPE Cable Underneath a Bridge on Underground Power Cable Systems

In this paper, XLPE cable underneath a bridge is modelled using EMTP/ATPDraw. Bridge section is also modelled by mutually coupled parallel conductor with XLPE cable. This paper is analysed the overvoltge by structure change of bridge section when the lightning occurs on the system.
