    It may be only related to the demolition stirring up a  cloud of dust around or settling on the insulators.

    As a side note special dust bombs are made for attacking and disabling open air substations - like rain drops in a thunderstorm, the presence of mixed particulates ,even if individually not very conductive, turns the originally uniform insulation into a series of unequal values capacitors in series, which then break down one by one, until with a sizzle and a pop, the last link is complete. I understand the bombs contain a mixture of graphite powder and sand, and to restart can take days
