The Lightning Current Measurement Based on Wavelet Transform

Abstract

The current model of the lightning process is established and simulated in this article, and aiming at the disadvantage that the hardware filtering de-noising method adopted in the general lightning measurement system can not effectively separate signals and noises in same one frequency channel, this article uses the wavelet transform to replace the usual hardware filtering method in the lightning measurement system in order to overcome the disadvantage, and simulate this method. The result shows that this method is feasible and effective, with certain theoretical and practical values.
