Partial Discharge Modelling Based on a Cylindrical Model in Solid Dielectrics
, 2008 Partial discharges (PDs) are harmful to electrical insulation as they may degrade the material. Consequently, a lot of efforts have been made to develop suitable systems for PD measurements and monitoring.

Partial Discharge Pulse Sequence Analyses-A New Representation of Partial Discharge Data
11th International Symposium on High-Voltage Engineering (ISH 99), 1999 Computer-based partial discharge (PD) data acquisition and analyses are common in use. Over the last two decades, there has been tremendous growth in PD data processing to extract information. There are efforts made to make data banks of different PD signature patterns based on $\phi-q-n$ measurements on insulation models.

Research on a Partial Discharge Expert System for the Diagnosis of Damaged Transformation Equipment
Applied SciencesPartial discharge (PD) characteristics are very important for the diagnosis of damaged transformation equipment. If the power transmission and transformation equipment fails, it will cause large economic losses, and thus prevention is better than ...

Study of surface discharge behaviour at the oil-pressboard interface
, 2013 This thesis is concerned with the surface discharge behaviour at the oil-pressboard interface. For large transformers this is classified as a serious failure mode because it can lead to catastrophic failure under normal AC voltage operating conditions ...

Application of electro-optic modulation technique for PD monitoring of power transformers
Partial discharge (PD) detection is an important technique for assessing the health of high voltage power transformers. A partial discharge signal within an oil-filled power transformer may reach a winding first, then travel along the winding to the ...
