Abstract :
The authors study about inception, propagation and termination of electrical trees in XLPE cable insulation. They address the problem relating to development of electrical trees under various transient voltage profiles and detail the method of generating the experimental database. Also the physico-chemical changes in the treed zone are analysed using Wide Angle X-ray Diffraction (WAXD) and through Fourier Transform Infra-red Spectroscopy (FTIR) analysis
