9.6 Isolation

The Isolation test, also known as a leakage test, is a
type of resistance test run over a period of time to look
for high-resistive faults. This test applies more
measuring voltage than standard resistance tests
(typically 100 VDC) over a longer period of time or
Soak Time.
The purpose is to allow the applied higher voltage to
leak through corrosion or high resistive faults, revealing
the fault by the drop in the measured resistance value.
Standard resistance tests use lower voltages (15 to 45
V) only for a short period of time.
Snapshot
The Isolation (also known as insulation resistance) test
shows how the pair insulation (that is PIC or paper,
pulp, etc.) may be lower because of long-term voltage
on the pair under test. (Remember that telecom signals
are full time.) This is especially important for power
span pairs carrying significant voltages over time. Be
aware that the continuous application of a voltage
tends to dry up moisture, and some faults may seem to
disappear. (You would see the resistance value
increase and thus improve as the test progresses;
however, the cause of the moisture is not resolved.)
Note: The test should be run with an open circuit at the
far end.
The Snapshot page shows
resistance values for each lead combination. The
parameters are as follows:
