| Abstract: | A typical insulation damage needle model of XLPE cable during installation and operation is constructed,and a generator of damp oscillation impulse voltage is developed.The PD pulse of the needle model is measured respectively under ac voltage and the damp oscillation impulse voltage.Some fundamental characteristics of the needle model under the damp oscillation impulse voltage and ac voltage are compared and analyzed.The feasibility of adopting damp oscillation impulse voltage in withstanding voltage test and PD measurement for XLPE cable is discussed according to IEC 60600-3.The method of evaluating the insulation state of XLPE cable on-site is investigated preliminarily in laboratory. |
