Abstract

This paper addresses the modeling of lightning performance of medium voltage air cable using Alternative Transient Program - Electromagnetic Transient Program (ATP-EMTP). By means of simulation using digital models and Transient Analysis Control System (TACS) features developed within the ATP-EMTP, the lightning overvoltage performance of air cable is analyzed. The analyses are made under the influence of direct stroke to wooden poles, to messenger wires and to nearby trees. The simulation includes models of air cable, messenger wire and distribution poles while considering other factors which are the frequency dependence of the cable parameters, models of wooden-porcelain insulation and shield wire. Adequate flashover model is useful for predicting the crest value of the overvoltages on the distribution line and also for assessing the accurate effect of providing different protection options for the air cables. Based on the simulation results, practical recommendations are proposed for improvement in the lightning performance of air distribution cables.
