Current Waveform Parameters of CN Tower lightning Return Strokes andM-Cornponents

Although several attempts have been carried out to derive statistics about eN Tower lightning
current waveform parameters, which are essential for the design of appropriate protection
systems, the results have been limited use because of the nature of the collected data. The
absence of both the continuous and continuing currents from the collected data, made it
impossible to distinguish between return strokes, which are the most destructive components
of the lightning flash, and the M-components. The aim of this proposal is to solve this problem
with the aid of the available extensive high-speed camera records. The results of this project
will not only provide proper data to engineers dealing with lightning protection problems, but
also answer many fundamental questions about the difference between return-stroke current
impulses and those that correspond to M-components.
