摘要

Paper deals with the time correlation between lightning strokes and protection relay pickups. On a line fault, the relay pickup is the first action registered by the protection relay. For this, the pickup time is taken for correlation with lightning data available from the lightning locating system (LLS). The conducted studies have shown the time differences between a lightning stroke and a relay pickup to be up to 28 ms in 85% of the observed cases.
