This document details the sheath testing procedure for all new polymeric insulated underground cables, which shall be satisfied before a section of underground cable can be accepted for connection onto the UK Power Networks underground cable systems.HOW IS THE TEST PERFORMED? The cable to be tested must be de-energized and each end isolated. Using a VLF AC Hipot, the test voltage is applied to the cable while the tan delta controller takes measurements. The applied test voltage is raised in steps, with measurements first taken up to 0.5U₀, or one half of normal line to ground operating .Refer to Testing of HV Cables - Supplementary Information -2945493 for further information.
