The only thing we can gain from this sorry tale is the typical data obtained from an appalling 400 metres local loop.
(The performance will be very familiar to
Walter, from his experiences in trundling his
wheelbarrow around and about in
Ewhurstshire.)
What has amazed me is the loop resistance results. Considering that one would expect an open-circuit pair to show infinity, the
green and
blue pairs are clearly useless.
The
orange pair is not that good, either. The insulation resistance has halved between the two successive measurements!
