nostr:npub1ackmr47dxyacuzsvhzftme8qhd7l6dlj0eeaugexlaq627fv7sqqcc778c dielectric strength of dry air at 0°C is 30kV/cm. For 90% moist air I found one source where it goes down to 8kV/cm. Temperature could be higher and there could be some other factors so let's divide it by two for a good measure. Even at 4kV/cm, he'd have to be less than 7cm away from the line to have it arc to him. But in the clio it looks like he's significantly further than that.
