Investigating the lightning effect on compact transmission lines by employing Monte Carlo method

This paper examines the outage rate caused by lightning strokes on compact transmission lines (TL). Compact and conventional transmission lines are different in terms of design and structure. Due to such differences, the previous lightning performance studies on conventional TL are useless in understanding the lightning performance of compact TL; hence, such studies have to be updated. In this paper, the aforementioned differences have been taken into the consideration. The lightning performance of compact TL has been studied by application of Monte Carlo method. Moment method is used to determine tower surge impedance by SuperNEC software and an approximate model has been introduced for tower modeling in EMTP-RV. After the accurate modeling of all components, backflashover analysis has been performed and at the end, the number of outages in the simulated sample size has been presented.
