Sažetak

For the selection and design of line surge arresters (LSA), it is essential to know the characteristics of the lightning current circulating through LSA.
When lightning strikes a transmission line, only a part of the lightning current circulates through LSA.
This part mostly depends on the point of impact, and the characteristic of the lightning strike current. The determination of the cumulative distribution
function of the lightning current circulating through arresters is presented in first part of the paper. It can be applied on transmission lines where LSAs
will be installed to protect the line against the effect of atmospheric discharges.
Second part of paper presents the calculation results of the cumulative distribution function of the lightning current circulating through arresters for
particular 110 kV transmission line located in an area with high lightning activity.
