【 摘 要 】

The results of full-scale experiments of lightning current flow through soil are presented. With the pulse high voltage generator the current of several tens of kiloamperes amplitude was created in soil on the length up to 70 m. The measured current and voltage profiles, the calculation of resistance and its profile between electrodes in soil are presented. The investigation of resistance value behavior was performed in case of several electrical breakdowns.
