Explore and Analysis in Uncertainty of Measurement System for Lightning Current Waveform Generator

The lightning signal has been a hot subject in the field of extra high tension and strong current. It is also one of the main sources of the space strong magnetic field pulse. This technology needs to be solved urgently that is to carry out accurate measurement of lightning signal. It is important in the understanding of lightning, the application of lightning characteristics and the lightning protection. The current simulation based on ray generation, fast signal acquisition and lightning waveform measurement data processing system. A detailed analysis of the measurement system and the measurement data of the system to obtain the uncertainty. This paper presents a test system of data samples, and the uncertainty of measurement and calculation of transfer, give complete measurement results for the lightning data.
