BETTER TRANSMISSION SYSTEM LIGHTNING PERFORMANCE BY ADEQUATE CHOICE OF TOWER FOOTING RESISTANCE
(1981)
Abstract
This paper presents an analytical approach use
for the calculation of transmission-line lightning
outages, bringing the attention to the development
of a universal chart for the evaluation of the impact
of to11er footing resistance on the outage rate,
providing an insight into the interaction of tower
grounding and tower insulation in establishing the
r eliability of a line. A particular tower design
is selected, and the number of outages is estimated
by one recent an efficient method available (2),
including weather statistics, and tower footing resistance
analyzed under individual bases. This method
can be used in specific designs for the selection
of the minimum grounding and outage cost.
