Abstract

In this thesis, three kinds of defects are artificially made on the inside and the surface of the epoxy resin bushing with internal voltage detection sensor, which is practically equipped into SF₆ gas insulated switchgear for a 22.9 kV distribution line, so that discrimination of three kinds of PD signals by means of phi-q-n pattern analysis method was performed
