Abstract
Back-flashover phenomenon is disturbances on the overhead transmission lin which caused by direct stroke on the ground wire and towers. Back-flashover w be occures in which voltage higher or same with the Insulator Critical Flashov the flashover happens on that insulator. It is very difficult to back-flashover analisys which direct measuring methode, th is reason to analyze with simulation by modelling the parameters on t transmission lines such as, tower model, insulator model, grond wire, phase w and grounding system based on IEEE Working Group model. In this research t parameters model that simulated by using EMTP/ATP Software 2005 version a using using tower model which recommended in Japan for lighting surge analys it is using Constant-Parameter Distributed Line (CPDL) tower model Minimum lightning current that can cause back-flashover using front time and t time of the IEEE standard 1,2 x 50 μs on phase A of 20 kA, phase B of 46 kA a phase C of 116 kA. While using front time and tail time of the CIGRE standa 3 x 77,5 μs on phase A of 18 kA, phase B of 45 kA and phase C of 97 kA. Bas on the calculation results of the simulation the number of strokes that can cau back-flashover on phase A of 5.98 strokes per 191.788 km/year, phase B strok per 191.788 2.058 km/year, and phase C of 0.33 strokes per 191.788 km/year. Keyword : back-flashover, Lighting, EMTP/ATP
