Factory testing of long submarine XLPE cables using frequency-tuned resonant systems

This paper addresses the principles of testing long submarine solid dielectric cables with AC-voltage, using up to date high voltage equipment with frequency tuning. It is shown that lengths up to 100 km or more is possible to test if all parameters affecting such tests are taken into account and treated accurately. Whether an AC or a DC solid dielectric cable is chosen, an successful AC factory test with enhanced phase to ground voltage, give high credibility to the XLPE technologies of today.
