A Double-Exponential Lightning Current Function Suitable for Use of Different Sets of Input Data

Abstract

A function to simulate lightning return stroke current as a sum of two exponential terms is presented. The exponent of the first term is a linear function of time, while the exponent of the second term is a power function of time with degree n. Compared with the function from IEC 62305-1, the proposed function offers slightly different front of the current impulse. In addition, this letter gives details how to obtain parameters of the proposed function that satisfy the given requirements.
