The computation of power frequen cy overvoltage and switching overvoltage in a model of110kV transmission network w ith a long line by software EMTP is presented in this paper.The results show tha t the power frequency overvoltage and switching overvoltage are all within the limita-tion of design criteria if the line is around200km
so it needs no speci al means to limit these overvoltages except some shunt reactors added on the lin e.
