How are underground cables tested after installation to ensure their integrity?

2025-08-14

Post-installation testing is crucial to verify the integrity and safety of the cable. We recommend conducting key tests before energization, including insulation resistance testing to check for electrical leakage and high-potential (Hi-Pot) testing to assess the cable's ability to withstand high voltage. For locating faults after installation, tests like the Murray Loop test can be used to pinpoint the exact position of a fault without extensive digging.
