Abstract This paper respectively studies relationships between evolution of phase-resolved partial discharge(PRPD) patterns and surface topography, surface roughness, surface conductivity of oil-immersed insulation paper and gas constituents within cavity during the damaging process caused by partial discharge(PD). According to PRPD patterns, the damaging process can be divided into five stages. At each stage, surface conditions of insulation are analyzed by optical microscopy, scanning electron microscopy, atomic force microscopy, and high-resistance meter. Gas volume is analyzed by gas-measuring model, as well. Meanwhile, PRPD patterns of different gas constitution are compared, and analyzed, as well as those of different surface-damaging conditions. The results reveal that during the damaging process, main discharging form within cavity alters between pseudo-glow (or glow) and spark; PRPD pattern for pseudo-glow chiefly depends on properties of weak electronegative gases generated during PD; while PRPD patterns for spark mainly determined by different surface damage conditions; PRPD patterns for spark manifest different levels of “rabbit-ear” and periodical features, whose levels mainly depends on surface trap density and surface conductivity, respectively, surface roughness will not change shapes of PRPD patterns, but discharge amount declines as its value increases.
