Abstract :
DC testing is extensively used to verify the dielectric integrity of underground cables after installation, repair or maintenance. Although DC testing is very simple and inexpensive (compact test devices), there is some concern that it could affect the lifetime of polymeric insulation. The debate has been raging for many years but there are very few reported studies to help determine whether DC testing should be eliminated and replaced by low-frequency (0.1 Hz) or oscillating-wave tests
