In this paper is carried out a study of lightning protection of 110 kV over-head line with using of overhead ground-wire cable and surge arrester. In this work are researched the main parameters of lightning, the consequences of lightning for current carrying elements and means of protection against lightning surges. The equivalent circuit of overhead power line was created in the EMTP software for the calculation of lightning surges. The main theme is the analysis of lightning prevention of line 110 kV with and without surge arresters. |
