I thought that as well Westie but the report says:
"Speaking last night a spokesman from the power company said: “We received a report from police at 11.02pm that a helicopter had come into contact with overhead power lines.
“Our engineers are currently on site and have established that a 132,000 volt overhead power line has been damaged.
“This interrupted power supplies to 373 customers, and others across a wider area would have had a flickering supply for a few seconds which then returned to normal."
Doesn't make sense if only a few hundred customers were affected. On the other hand there are 132KV lines visible in the photo of the downed chopper, assuming of course it's genuine.
