Comparative Analysis of Four Lightning Current Measure Results with Lightning Location System
-
Abstract
The waveform and amplitude of lightning current are important foundation parameters for lightning protection design and transform of electric power equipments. In this paper, high accuracy lightning current measure devices with the function of GPS clock and positioning are fristly developed, and the lightning current parameters in the region of China Southern Power Grid are accumulated by monitoring of lightning directly stroke on high tower and artificial rocket triggered lightning test, the measure results between the lightning current measure device and the lightning location system of CSG are comparative analysis lastly. The four lighting current measured results indicate that the position accuracy of lightning location system is reach to a high accuracy of 172 m to 675 m while the amplitude accuracy is varied from -22.8% to 4.5%.
