Abstract :
This paper summarize results from work on diagnosis of medium voltage (MV) XLPE cables with respect to water treeing performed at KTH, Stockholm. The work, performed both in laboratory and in the field, has shown that high voltage dielectric spectroscopy is a good tool for diagnosis of MV XLPE cables and that it is able to differentiate between different stages of water tree ageing
