This paper presents experimental results of lightning surges incoming into a customer due to lightning
to an antenna of the customer, a pole and a ground nearby the customer, and briefly discusses lightning
current distribution in the customer, a distribution line and a telephone line. Based on experimental
results, modeling of each component is explained, and EMTP simulations are carried out. The ground
voltage rise is represented by a mutual resistance between grounding electrodes. EMTP simulation results
have been observed to agree qualitatively with themeasured results, and it becomes possible to investigate
lightning surges and current distribution in a customer by an EMTP simulation.
