Sažetak
The overview of the outages of 110 kV overhead lines has been given in this paper. Correlation of the relay protection tripping data and lightning location systems (LLS) data has shown the impact of the lighting on the operation reliability of the overhead line. The EMTP/ATP software has been used for simulation and analysis of power system performance with respect to lightning overvoltages in cases with and without line surge arresters. The input data for the simulation are data on lightning strokes which caused the relay tripping of the overhead line obtained from the relay protection system and LLS. Simulations have proved the relay protection system and LLS performance.
