Test 2: Test for short circuits .
Measure the resistance between the + pole and the - pole.
Connect an ohm meter between the two poles.
The measured value should be more than 100k
Ω for a cable
with a maximum length of 2 km.
The CS4000 control unit will report which short circuit
isolators that have been activated. The short circuit failure is
located between the activated short circuit isolators.
Test 3: Test for earth failure.
Measure between the + pole and the - pole respectively and
earth to detect an earth fault. Connect the ohmmeter b
pole and earth. Measure and thereafter repeat the procedure for
- pole.
The measured value should be more than 50 k Ω for a cable
with a maximum length of 2 km.
The CS4000 control unit will report in which detector loop or
central the earth failure has occurred.
Proceed as follows when you want to locate an earth fault.
1. Divide the cable in two halves, locate the earth fault.
2. Divide this half in two halves and locate the earth fault.
3. Continue to divide the cable into halves until you have
found the exact position of the earth fault.
