Observation of lightning current in the soil by rocket-triggered lightning

2016 33rd International Conference on Lightning Protection (ICLP), 2016
In recent years, there has been a significant increase in the damage to electrical and electronic devices owing to lightning surge-induced overvoltage/overcurrent, in Japan. In particular, the lightning surge overcurrent that flows through grounding lines can cause serious damage to electronic equipment.
