Tony Ray may be able to answer this;
What length of water stream could be considered an insulator ?
I know that they clean insulators on big power lines from a helicopter but
I have often thought they could do it with a pulsed stream of water.
That way there would be no continous water path.
Perhaps the risk of the pulsing failing would be too great.
At one emergency management committee meeting I attended there was a discussion
about the problem when a big storm brings down lines that might be live.
The problem is after a really big storm it might be a day or two before the
electricity supplier could get to the site.
The question was could some one from SES be trained to make safe.
With wires laying in the street for a considerable time it presents an
increasing risk that the area cannot be guarded and access has to be provided.
The whole idea of some one else sorting out the problem was booded down
very smartly.
However no solution was offered.
