Abstract
The space charge in water tree degraded LDPE has been measured by the thermally stimulated current (TSC) method. The shape of the TSC spectra does not change with the degradation of polymeric insulation containing water trees, but the TSC peak increases linearly with the increase of the length of the water tree. It is shown that the TSC measuring method can adapt to evaluate the degradation caused by water treeing
