Study Of Lightninig On Transmission And Influence Of Arrester And Tower Footing Resistance For Damping These Transient Overvoltages
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2015, Vol 9, Issue 8
Abstract
One of the important problems of power systems is lightning that has always been the main challenges of transmission lines. In this paper, overvoltages caused by lightning on the insulator chain, and transformer will be examined. Then arresters and footing resistance in this process will be studied. In this study, insulators chain overvoltages will be used in two modes: (1) at the moment of thunderstroke on tip of tower (2) thunderstroke on guard wires between two towers in substation terminal towers. After this, in the process the influence of overvoltages on the footing resistance, transformer and influence of arrester in overvoltages reduction will be calculated. Simulations have been implemented on EMTP software. The study was carried out on an actual power network in south of Iran (between Bandar Abbas power plant and substation-wing) at 400 KV voltage level.
