Special Applications
1.1 For resistance faults at more than one location on a
pair, the resistance fault locate operation gives a
distance to the average of the fault locations. For
example, if a 3000 ft/914 m cable has one 10k ohm fault
at 1000 ft/304 m and a 100k ohm fault at 2000 ft/610 m,
the unit should show a 9.09k ohms fault at about 1091
ft/333 m (the average), or just past the major fault.
Unit averages the distances to the faults
and shows the distance-to-fault to be here.
