High voltage electric pylons and torrential rain?
Heavy rain will tend to clean the insulators, rather than
inducing tracking.

Nothing special, most obviously wih the glass insulators
on 350KV and 500KV transmission lines.
Don\'t they become surface conductive to ground?

Walk past any major substation during hot humid weather and the
buzzing is quite alarming.

Nope, if they did, the line would shut down.
But I don\'t understand how it doesn\'t happen. They are throwing water
spray to them, a lot of water, from below.
The entire surface of the glass must be getting wet.

Water by itself is not that conductive. It is impurities in it that make
it conductive. Ultra-pure water has a resistance of up to 18 megohm per
cm. They won\'t be using that, but apparently use de-ionised water, which
is fairly free from impurities and thus not particularly conductive.

They are shaped like umbrellas so that they stay partly dry when it rains.

Sure, with a lot of voltage, ballpark a megavolt/meter.
There could be a tiny current from droplet drift, too.

Cool, just wondering since I was spraying mist on a parrot and he was rather close to a light socket.
