| Abstract: | This paper presents the main factors that affect the insulation of the circulating XLPE power cables. The power frequency withstand test is one of the prevalent methods because it's experiment status is close to the circulating status of the XLPE power cable. This paper shows the the influence of power frequency voltage withstanding experiment on the diagnosis of mechanical damnification, evaluation of damnification degree and the influence of the damped time thought experimentations. And the paper indicates when the insulation isn't affected by damp, the power frequency withstand test can't check up the damnification. |
