In this paper, we discussed partial discharge (PD) inception characteristics and V-t characteristics of PD inception in liquid nitrogen (LN2)/polypropylene laminated paper (PPLP®) composite insulation system for high temperature superconducting (HTS) cable. Experimental results revealed that the magnitude of initial PD was in the range of 2.0-30 pC irrespective of butt gap condition and the initial PD was generated at the first and third quadrant of voltage phase independent of the pressurized condition of LN2. Furthermore, life time indices n of V-t characteristics at PD inception were experimentally identified and the dependency on the pressure of LN2 was clarified.
