Abstract
Reduction of the overhead lines back-flashover rate (BFR) after application of special lightning protection systems is analyzed in this paper. The following lightning protection systems are considered: line arresters, underbuilt wires, additional shield wire and guy wires. Partial or combined efficiencies of mentioned lightning protection systems are analyzed. Overhead distribution (35â¯kV) and transmission (110â¯kV and 220â¯kV) lines BFR are estimated through the semi-statistical calculation procedure as suggested in international technical documents. System equivalent circuits in the EMTP-ATP software are created with carefully chosen models and parameters of elements. Pursuant to the estimated results, conclusions about application possibilities of different lightning protection systems are given.
