The overhead transmission lines stretching thousands of miles, accounted for a large part of power system, and lightning transmission line fault is the most main form of power system fault. In order to reduce the transmission corridor area, double circuit and even more loop transmission lines were more and more adopted, and therefore the tower is higher and higher. And the higher the tower, the greater the possibility of being struck by lightning. Thus it is very necessary to research and analyze the tower double circuit transmission line. The model of canal 110kV substation was established and the lighting withstands level and flashover phases were analyzed through the electric transient simulation program ATP-EMTP.

“…The multistory tower model consists of a line of parameters distributed with parallel RL circuits and has been recommended by Japanese standards for designing/coordinating insulation against lightning. This model is widely used for lightning wave analysis in Japan [13][19] [20]. The velocity of propagation is 300 m/s.…”

This simulation study presents the effect of lightning strikes on the performance of arresters at 150 kV overhead lines. Lightning strikes have several parameters that affect the performance of line arresters (LA), namely lightning charge, and impulse energy. The simulation was attempted by injection of a direct strike to the ground wire with the peak voltage of 10 MV. The peak voltage was varied in terms of wavefront time (Tf) and the duration of lightning impulses (tau). In order to calculate current, charge and impulse energy of LA from various variations of Tf and tau, the trapezoidal numerical integration method is used. The current and impulse energy arising due to direct strikes and various variations of Tf and tau will be compared for each phase so that the influence of Tf and tau can be obtained from the performance of the LA and the current charge and impulse energy values are still within the limits of the IEEE C62.11 standard. The installation of LA and the position of arresters affected the peak voltage of lightning on the phase line when lightning struck it. The line arresters provide a drop in the peak voltage of lightning in phase lines. By installing line arresters in each tower, it will reduce the peak voltage of lightning on the phase line more significantly than the standalone line arrester. It is shown that the line arresters have to install at least six towers to reduce the peak voltage in the phase lines.

“…Strikes have caused extensive damage to electrical equipment of the Tenaga Nasional Berhad (TNB) power system [3], and it is estimated that about 50-60% of tripping of the TNB's power system, especially of transmission and distribution networks, has been caused by lightning [4]. In order to reduce this number, TNB has been conducting numerous studies to ensure the reliability and sustainability of the electrical power supply [5].…”
