Abstract
The paper deals with surge phenomena on hv and vhv three-phase transmission lines with earth wire. The impact
of lightning stroke into the earth wire and its influence on parallel phase conductors is investigated. The model of
the transmission line is created by network with distributed parameters and concurs on our previous paper. In
this paper are derived basic equations respecting not only inductive and capacitive coupling among phase
conductors but they involve the coupling phase conductors to the earth wire, as well. Problem is solved
numerically in the time domain. Some examples illustrating the propagation of surge wave caused by lightning
stroke are solved here
