This work aims to encourage the application of partial discharge measurements in electrical equipment Brazil through practical utilization T-F Map (Time-Frequency Map) tool, applied separation multiple sources discharge. Partial were performed on rotating machines and medium voltage cables. The made with a stator 5000 hp three-phase induction motor, while cable carried out during an artificial ...

During the ageing of in-service medium voltage equipment, electrical losses are mainly due to partial discharges. These partial discharges can lead to the electrical failure of industrial equipment [1]. Partial discharges include (i) bulk discharges occurring in insulating material voids, (ii) corona discharges affecting or not the insulator and (iii) surface discharges developing on an insulat...

Polymer nanocomposites have recently been attracting attention among researchers in electrical insulating applications from energy storage to power delivery. However, partial discharge has always been a predecessor to major faults and problems in this field. In addition, there is a lot more to explore, as neither the partial discharge characteristic in nanocomposites nor their electrical proper...
