Control of insulation condition of smart grids by means of continuous PD monitoring

Abstract

This paper presents the monitoring architecture and experience gained in a pilot distribution grid designed for continuous control of insulation condition of the grid by means of PD measurements. Powerful data processing tools are used for the discrimination of PD pulses from background noise, for locating different PD sources, for clustering PD sources and for identification of the defect associated to each PD source.

Artificial Neural Network Application for Partial Discharge Recognition: Survey and Future Directions

“…Over the years, partial discharge (PD) recognition has been a topic of interest for a number of reasons, in particular the need to distinguish between different PD fault sources within the insulation systems of power apparatus and discriminate them from extraneous interference events considered as noise [1][2][3][4][5]. PDs are the electrical discharges that occur within or outside the insulation of a high-voltage (HV) system under electric stress [6,7].…”

Electrical Characteristics of Silicone Rubber as Insulation Materials

“…Silicone rubber is one of the important polymeric insulators which are widely used nowadays in indoor and outdoor insulation. In order to improve the performance of silicone rubber at different weathering conditions, Inorganic filler (Alumina tri-hydrate) is added to it with different concentrations to reach the suitable percentage of filler to maximize the insulator life time [11][12][13]. Polymers are macromolecule built up by linking together a large number of smaller molecules which are termed monomers, and the reactions by which they combine are termed polymerization reactions.…”
