Abstract

In order to analyze and diagnosis on Location of partial discharge in underground distribution cable, partial discharges were measured using eletromagnetic sensors, oscilloscope, PDMS system at on-site underground multi-circuit switches. Throughout the analysis using 3-phase simultaneous pulse analysis and pulse polarity comparison of circuits, it is possible to separate noises and PD pulses and to find out the location of the pulses.
