Abstract

This paper describes the lightning overvoltage protection schemes of cable laterals connected with MV overhead line. The various protection schemes are modelled and investigated are carried out on the simulation results. The simulations are performed using EMTP-ATP simulation environment, which is a strong tool to analysis transient behaviour of MV network components. The simulated lightning surge is struck on one of the overhead line phases and overvoltage effects are investigated down the cable connected with overhead line. The cable laterals are consisted of sub-laterals which are also simulated in this study. Generally, the surge arresters are installed at the junction of overhead line and cable and at far end of the cable. The various mitigation methods and protection schemes for protecting MV cable laterals are proposed on the basis of surge arresters locations, sub-laterals connections, and cable length.
