RE: O.H.L
But yes, actually Keith's way is the easiest and cheapest solution!
On some systems the fault isa located as a function of distance from a substation (impedance relays), but it is more in use on transmission-lines - HV, EHV and UHV systems. I have not seen it been used on MV-systems - but it might work on a long line with no T-offs.
Sometimes it is not easy to spot failures, like a crack on an insulator. On a big network (lots of T-offs and segments) the best would be to use the test and eliminate technique - divide the line in different segments and eliminate the healthy sections - working towards the fault.
Hope it helps
