Sažetak
One and a half year after the installation of the line surge arresters (LSAs) to 110 kV overhead lines (OHL) on the island Brač it is possible to obtain representative statistical analysis results. The correlation of the relay protection tripping data and lightning locating system (LLS) data proved the impact of the lightning on the operation reliability of the overhead lines. Number of outages was analysed in relation to the lightning statistics for the observed area. Case by case analyses of the outages were performed in order to identify which towers of the overhead lines are endangered due to their exposure to the lightning discharges. Conclusions on line surge arresters lightning performance and possible improvements of their configuration will be considered.
