Abstract :
Problems related to the classical DC test and to the way this test is usually carried out in practice are examined. Information is given on alternative after-laying tests, particularly the oscillating wave test, recommended by CIGRE. The oscillating wave test has been applied several times as an after-laying test on long-length 150-kV XLPE (cross-linked polyethylene) cable systems. Although this test method is more complicated and more expensive than the DC test, experiences so far show that it is promising
