This paper presents the analysis and observation results of the induced voltage waveforms caused by nearby natural lightning on overhead power lines in the Guangzhou field experiment site during the summer of 2008. Peak values of the induced voltage for 36 natural lightning return strokes ranged from 0.21 to 3.87 kV. And the double-peak oscillation phenomenon can be found in the waveforms. The interval...
The article focuses on the residual voltage characteristics of surge protective device during natural lightning induction based on the field observation and lab tests. In natural lighting, induced voltage waveforms and amplitudes generated on the live conductor and the neutral conductor are basically consistent, the amplitude and steepness of the voltage at the household side are higher than those...
This paper carries out a summary and analysis on the observation result of induced voltage waveforms caused by nearby natural lightning on 220-V rated low-voltage overhead distribution lines in Guangzhou Field Experiment Site for Lightning Research and Testing (GFESLRT) during Summer 2008. It can be observed that when surge protective device (SPD) is not connected, the maximum peak value of induced...
