“…Its result may influence traditional concepts relating to lightning protection terminal systems. In our previous work, a method has been provided to calculate return stroke currents at ground level [4]. Differing from other return stroke models, it is convenient for this method to obtain return stroke currents with various resistance values at the base of the channel.…”

A new method, which simulates the lighting channel as a series network of -circuits, has been proposed by the authors. It successfully calculates the return stroke current with various added resistance values at the base of the lightning channel. The calculation shows that the peak current and current risetime along the channel are strongly influenced by the added resistance element at ground level. However, the larger voltage across this resistance element may cause the flashover along its surface and result in failure of current limiting. This paper describes the analysis and simulation of a novel method of current sharing following the termination of a lightning stroke onto a resistive lightning protection terminal. Such a system of resistance elements is essential to ensure that surface flashover does not occur across lightning rods and current limiting is successful.Index Terms-A resistive lightning protection terminal, flashover voltage, lightning discharge, peak current, return stroke current, voltage across rods, withstand voltage.
