要約(英語): In order to prevent lightnings from penetrating blades of wind power generators, we have been investigating factors that spark discharges penetrate insulators. In this paper, we measured the maximum pressures of spark discharges using a pressure measurement film that discolorations with pressure. We applied negative lightning impulse voltages between electrodes and hit spark discharges on the pressure measurement film. As a result, we observed discolorations due to spark discharges and upward leaders on the pressure measurement film. Furthermore, we discussed the cause of the pressure generated by spark discharges.
