This paper introduces advantages and disadvantages of ultrasonic wave and UHF testing techniques for GIS. Simulation platform for 252 kV GIS partial discharge is established and the phase angle difference of primary and secondary voltage of the platform is tested. Point corona discharge defects of conductor and shell are set, and testing signals are obtained by means of the simulation platform. Thus, the paper analyzes the characteristics and laws of UHF and ultrasonic wave signals in case of such defects , providing references for live detection and diagnosis of GIS.
