Modelling of 132kV overhead transmission lines by using ATP/EMTP for back-flashover pattern recognition / Nur Zawani Saharuddin

Lightning overvoltage is the major cause of transmission-line outage in Malaysia. The phenomenon is a dominant factor considered in designing substations and transmission-line insulation, so its investigation is important. This study is thus essential to ensuring consistent performance of transmissi...
