Well there are many things now done. Firstly of course if power does go
down, its not rocket science if power is at one end and not the other and
yes, things are monitored and obviously when this happens a section is
isolated and an attempt is made to route around it. This normally works if
its a small area, but larger areas of course are protected in that you
cannot overload a section any more, the logic stops that being possible, in
theory at least.
Also some power companies use a thermal imaging device on a helicopter to
regularly look at power lines as odd heat increases spells possible failure
and they can fix it before it becomes an issue.

Underground cables are the most difficult of course as there is no way to
find where the break is unless there is a tell tale crater in the ground
nearby of course!

The woman on the phone at Western Power could say precisely that they
were aware of the fault and it had affected 218 properties! Pretty
f.... amazing, if you ask me.
