Abstract :
Lightning performance of 22 kV overhead distribution lines has been investigated using lightning protection design workstation (LPDW). Shield wire and surge arresters play a significant role for protecting overhead distribution lines. The line with shield wire can reduce the number of flashovers in open ground and number of flashovers with nearby objects. The application of surge arresters provides better performance than shield wire, improving the lightning performance by installing surge arresters at every pole provides the best protection. The affects of footing impedance and also shield wire size have been analyzed.
