Abstract

On-line partial discharge (PD-OL) monitoring systems for medium voltage cable connections have recently been introduced in Dutch grids and also a few worldwide. The vast continuous stream of diagnostic data calls for a re-evaluation of statistical methods to be applied for the interpretation of the PD activity. In the present paper a variety of statistical parameters are discussed. These parameters include parameters for observing trends in PD activity over time. The methods are applied to data obtained from several continuous online field measurements collected over a year. The results of analyses on several weak spots which were detected before failure are presented. Results of failed accessories are discussed in relation to their prior PD behavior.
