Abstract

This paper investigates the 1000 KV UHV transmission line under the 100 KA lightning impulse on the
overhead guard wire with considering the corona phenomena and soil ionization in high frequency
grounding system. In this study, four cases of transient electromagnetic current status of the transmission
line power system have been analyzed with EMTP-RV software. The results of this procedure depict that
the soil ionization in the absence of the corona phenomenon can be caused an attenuation of the lightning
current waves. But with considering the corona phenomena and Soil ionization, all together, this
reduction of the resultant waves propagation from a lightning strike on a 1000 KV UHV transmission line
is not visible due to high charging of the corona phenomena.
