Sažetak
In the operation of the broadcasting transmitter, during a lightning storm, comes to frequent surge arrester failures in the switchgear of the broadcasting transmitter and along the 10 kV supply cable (surge arresters in the cable section boxes). Analysis of lightning strokes to the broadcasting transmitter is given in the paper. EMTP simulation of surge arresters loading was conducted. The energy overload of surge arresters is due to lightning flash with more than one lightning strokes or more lightning flashes in short time. Recommendations were also given for improvement of existing surge protection and reduction the number of surge arresters failures.
