not the best edited video, but a good illustration, ~I wonder if whoever nicked the HV earth drop wire got a belt as they cut it.
~It may be the leakage current reduces to a much safer level when it's not actually snowing.
As wood is not a good conductor, you do not need that many mA to get enough heat to get the wood to burning temperature, but you do need a good few volts to push the mA through - I presume here about 7000 of them from line to earth in this case.
Had it been a lower impedance to ground, I'd have expected the 11kV protection to trip.
