Abstract
An emerging of new material, XLPO, has now been widely used as power cable insulation and it is necessary and compulsory to perform compliant standard test. According to the IEC 60270, partial discharge (PD) test is the promised and nonintrusive method to determine quality of insulation. In this paper, XLPO insulation of the unshielded cable has been preliminary tested by measuring its PD behavior under different temperature exposure. The experimental results illustrate that occurrence of partial discharge inception voltage (PDIV) forms as parabola with a convex trend under temperature variations. It is also found that XLPO is less susceptible to PDIV when compared to PVC insulation under the same conditions.
