The partial discharge (PD) measurement is a very well known possibility to assess the quality of an insulation system. The aim of the PD-diagnostic is the detection of destruction of electrical insulation as a result of electrical stress especially of PD during operation.

Microsensors for Partial Discharge
2008 International Conference on Advances in Electronics and Micro-electronics, 2008For longer service life and better reliability of high voltage under stressed parts or of such whole systems, facilities for deep investigation are necessary. Extremely small microsensors which can be integrated during the production inside measured object like high voltage transformers, drivers or high voltage parts of PCB's are, can serve us valued ...

Recognition of partial discharge patterns
2012 IEEE Power and Energy Society General Meeting, 2012This paper aims to provide a robust data mining framework for partial discharge (PD) pattern recognition, specifically to classify the PD signals based on their shapes. The framework contains feature extraction (FE), feature selection (FS), unsupervised clustering analysis and clustering result validation.

This chapter is devoted to the measurement of partial discharges (PD) localized in weak spots of dielectrics if subjected to high test voltages. As standards for PD measurement s have been introduced only for quality assurance tests of HV apparatus energized by power frequency AC voltages (50/60 Hz), the following treatment refers mainly to this test ...

A contribution in partial discharge detection
IEEE Instrumentation and Measurement Technology Conference Sensing, Processing, Networking. IMTC Proceedings, 2002The proposed system allows the measurement of: 1. Apparent charge by means of direct analog integration of the current induced by the PD event; 2. The corresponding value of the applied voltage "V" 3. The time instant in which the Partial Discharge occurs "t/sub PD/". This particular instrumentation, devoted to the measurement of partial discharges, is

Partial discharge. XVII. The early history of partial discharge research
IEEE Electrical Insulation Magazine, 1993For pt.XVI see ibid., vol.9, no.3, p.21 et seq. (1993). Early investigations into partial discharge (PD) phenomena are reviewed to illustrate how little has changed and how much has, in some respects, been repeated during the forty years from 1940 to 1980.

IEEE transactions on dielectrics and electrical insulation, 2020
Recent studies have demonstrated that fluoronitrile (FN) Novec™ 4710 and fluoroketone (FK) Novec™ 5110 show higher dielectric strength than SF6. These gases can be mixed with a buffer gas such as CO2 and technical air to have suitable dielectric ...

Preliminary partial discharge measurements with a computer aided partial discharge detection system [PDF]
Partial discharges (PDs) can be destructive to electrical insulation as they may degrade the material in time. Consequently, studies have been made to develop efficient systems for PD measurements and monitoring. Due to the complexity of PDs as well as factors that can affect PD characteristics, the research on PD measurement is still active.
