Abstract :
The authors report the results of an investigation of changes in polarisation in field-aged cross-linked polyethylene by dielectric spectroscopy over a wide frequency range. They also provide an electrical analog circuit representation of the dissipative, capacitive and resistive components of the field-aged XLPE cables as functions of frequency
