As concluded
in Chapter 5, the CIGRE distribution will continue to be used. It is the proper
distribution when considering flashes to the ground wires or towers. However, it is
debatable whether this distribution should be used in calculating shielding failures.
As reported in Chapter 6, a current distribution to ground that is developed from the
CIGRE distribution may be more appropriate, and using this ground level distribution
results in higher shielding failure rates, or requires smaller design angles. This
will be discussed further in this chapter.
