They carry a heat sensor usually.
Joints (splices) in power lines can get corroded. That then can cause "hot spots" which can ultimately trigger failure, or worse still, bush fires.

It is a normal way of monitoring long stretches of power lines in rural and remote areas, as Martin has indicated. 

Victorians will understand the cost of not maintaining power lines properly.

Yes this is off topic.

For at least the 90 minutes, there has been a helicopter flying loops over my GBS site in west Kambah (yes, mostly more than 100 metres and it is now it is more distant) with what looks like someone looking out the side. Such persistence is very odd. I thought maybe police tracking a fugitive. The abdomen of the helicopter carries the field mark of ActewAGL. I phoned and was eventually advised it is surveying infrastructure to look for equipment faults and fire risks. Strange but that is what I was told.
