Application of Lightning Location System Data for Designing the External Lightning Protection System

This paper deals with designing and positioning of air-termination system and analyzes the effectiveness of external lightning protection system (LPS). The electro-geometric model based on rolling sphere method was used to determine the optimal height and number of air- termination installations in the oil refinery according to standard IEC 62305. The lightning parameters are essential input variables for estimating the effectiveness of external LPS. Lightning parameters derived from lightning location system (LLS) observations were compared to ones used in IEC standard. For this purpose an algorithm for assessment of the lightning flash multiplicity was developed in order to determine the current amplitude probability distribution of the first cloud to ground negative strokes. Analysis of LLS data show there is higher probability of low amplitude cloud to ground strokes occurrence compared to IEC standard. Consequently, for a given lightning protection level (LPL), the risk of the lightning terminating at the object to be protected is higher.
