Simulation and Analysis of Lightning Backflashover for the 132 Kv Kuala Krai–Gua Musang Transmission Line Using PSCAD

Lightning has been a major concern to the power system researchers as it may cause damage to the connected electrical equipment especially to the transmission line. One of the event that will cause lightning overvoltage and most likely to occur is backflashover. For that reason, one study has bee...
