Two ideal, elementary valve blocks with a rated
voltage of 1 kV for lightning discharge currents of 5 and
10 kA respectively were considered. A ratio γ of 0.02 was
found to be adequate for the response of the model.
Because the value of γ will determine the finally value of
L1, it will indirectly influence the time lag of the residual
voltage peak and indeed the form of the well known [2,3]
hysteresis cycle. The Table 1 summarizes the V-Icharacteristic
for these valve blocks and the currents into
the branches A0 and A1.
