This paper investigates the characteristics of PDs\r\ncaused by metallic particle adhering to the solid spacer. The PD\r\ndetection and measurement were carried out by using IEC 60270\r\nmethod with particles of different sizes and at different positions on\r\nthe spacer surface. The results show that a particle of certain size at\r\ncertain position possesses a unique PD characteristic as compared to\r\nthose caused by particles of different sizes and\/or at different\r\npositions. Therefore PD characteristics may be useful for the particle\r\nsize and position identification.","references":"[1] H.
