title = "Back Flashover Performance of 500 kV Double Circuit Transmission Lines Struck by Lightning",
abstract = "Effective electricity transmission system is critical to the power system stability at the consumer ends. To ensure an uninterruptible supply, the insulation of the transmission lines must be evaluated and coordinated. Research has shown that lightning contributes the largest percentage of outages in tropical countries. This work presents an Electromagnetic Transient Program (EMTP)-based back flashover performance evaluation for 500 kV double circuit transmission lines during lightning events in Malaysia. The main parameters considered are the resistance of the tower footing and lightning current waveshapes and magnitudes. The results found that those parameters influence the reliability of the transmission system during lightning incidence. Hence, the need to devise an adequate protection system is necessary. The findings from this work are useful to electrical utilities for identifying root causes of the transmission lines back flashover occurrence.",
