Abstract According to the characteristics of lightning current, and combining with some
parameters of lightning current, three main lightning current mathematic models such
as bi-exponential function model,Heidler model and impulse function model were
analyzed by MATLAB and distinctions among different models and their applicability
were obtained, which is helpful in doing research on characteristics and reducing the
harm effects of lightning.
