VI. CONCLUSIONS
A procedure for the computation of the lightning
currents distribution is presented. The metal conteiner
is simulated by means of an electrical network whose
analysis is carried out by using the SPICE program.
The ionization phenomena in the soil is simulated by
means of non-linear resistances and their influence on
the current distributions is examined.
In order to point out the influence of the non-linear
ground impedance, Figgs. 6 show the transient
behaviours of the currents through two points of the
structure with reference to three values of the ground
resistivity.
The maximum values of the transient currents at the
points Pi-Pi4, for two values of the ground resistivity,
are shows in Figgs. 7.
