typical network fault, burnt out pole fuse.
Overtime the springness of the metal contacts in the fuse holder gets weaker, eventually good contact isn't made causing a high resistance and eventually burns out. Things like cycling of high and low current draw, the overhead lines swinging in the wind all contribute to this happening. It could have even been a loose connection from when originally installed failing.
An odd word for 'fuse' when 'fuse' is a perfectly fine word...!
Mind you, a local newspaper report of a car flipping into a roadside ditch said that the car "ended up in the water table by the side of the road"!
Sounds like he was just using a generic term for the lines "cutting over" to your property as there are a number of points up the pole where it could fail. None of these could be monitored by yourself unless you can see that the cable has come right out.
At the line tap off the lines themselves
At the top (incoming side of fuse) of the fuse holder, some fuses have all the cables come in the bottom so might not look like this
Internally to the fuse holder (springs, screws, blown fuse)
The bottom (outgoing side of fuse)
Another possible fault I have seen is that the fuse blows but current continues to flow through moisture in the fuse holder, generally not enough to run much but potentially could run light loads poorly.
You can also have faults in your cable where the neutral connects, its common to use Neutral Screen cable which is wrapped around the phase conductor and then split off at each end. I have seen this copper get scored when the cable is stripped and this leads to corrosion down in the crutch of the cable which is hard to find without removing further insulation.
If you have overheads cable nearly all of these same faults can occur in your point of entry box as well (POE).
If the main cable goes down one side the road, and your house is on the other, a cutover could be the cable that comes across the road to a pole on your side and then either overhead or underground the rest of the way in.
