PD data analysis and evaluation of partial discharge patterns for uniform characterisation
IEE Proceedings - Science, Measurement and Technology, 2004A modern partial discharge (PD) analyser provides a complete record of PD events obtained during the time of observation. A variety of analysis techniques can be applied to the data to extract characteristic information. An analysis technique that would support instrument-independent characterisation needs to have a method of identifying characteristic

Signal extraction methods for online partial discharge (PD) measurement of power transformers
2015 IEEE 11th International Conference on the Properties and Applications of Dielectric Materials (ICPADM), 2015Wavelet transform-based Partial discharge ( PD) signal extraction methods have been widely adopted in the past ten years. However, these methods may still encounter some difficulties in online PD measurements, in which PD signals can be overwhelmed by noise.

European Transactions on Electrical Power, 1996
AbstractIn this paper some possibilities of further applications of a known “Streamer Partial‐Discharge Model” are proposed. These possibilities refer to the relation between the observed partial‐discharge (PD) magnitude and the applied field to the insulation.

Proceedings of 2005 International Symposium on Electrical Insulating Materials, 2005. (ISEIM 2005)., 2005
This paper introduces a novel technique for partial discharge (PD) measurement and analysis: PD-CPWA (PD current pulse waveform analysis). PD-CPWA focuses on the PD current pulse waveform and its time transition from PD inception to breakdown (BD), which is closely related to PD mechanisms in electrical insulating materials.

IEEE Electrical Insulation Magazine, 1992
For pt.XIV see ibid., vol.8, no.5, p.34 (1992). The effects of X-ray irradiation during partial discharge measurements are discussed. The partial discharge phenomena in cavities is detailed. A full-scale system capable of testing 138-kV-class post insulators under combined electric stress and X-ray radiation was implemented.

Partial discharge. XXI. Acoustic emission based PD source location in transformers
IEEE Electrical Insulation Magazine, 1995Acoustic emission-based partial discharge source location has been applied successfully to power transformers in both factory and field environments, and this method is becoming an established test procedure with a high success rate. With the aid of local utilities and utility laboratories that use acoustic emission apparatus daily, we expect further ...

Detecting and Monitoring Insulation Failure: A Review of Partial Discharge (PD) Detection Techniques
International Journal of Advances in Engineering and ManagementThe reliability and efficiency of electrical systems vitally depend on electrical insulation to prevent electricity leakage during transmission. However, due to various operational and environmental factors such as humidity, thermal stress, and others, insulation materials degrade over time. Therefore, detecting and monitoring insulation degradation at
