Partial discharges. XII. Partial discharge detection in rotating electrical machines
IEEE Electrical Insulation Magazine, 1992For pt.XI see ibid., vol.8, no.2, p.14 et seq. (1992). Partial discharge (PD) phenomena in the windings of rotating machines are examined. PD measurements on rotating machines, both offline and online, are described. Data acquisition and analysis requirements are briefly considered. >

Partial discharge. XIV. Acoustic partial discharge detection-practical application
IEEE Electrical Insulation Magazine, 1992For pt.XIII see ibid., vol.8, no.4 (July/August 1992). The finer points of acoustic partial discharge (PD) detection systems and their common applications are treated. The PD source, propagation path of the waves, the acoustic sensor, and system noise are described.

Electric conduction breakdown and partial discharges in dielectric fluids. I. Partial discharges
[1991] Proceedings of the 3rd International Conference on Properties and Applications of Dielectric Materials, 2002Some studies have suggested that there may exist a relationship between conduction and electrical breakdown. Before such a correlation between these phenomena and partial discharges (PDs) can be investigated, it is necessary to produce reproducible PD data.

Partial discharge. XIII. Acoustic partial discharge detection-fundamental considerations
IEEE Electrical Insulation Magazine, 1992An overview of the basic acoustics theory required to understand the finer points of acoustic partial discharge (PD) detection systems is given. PD and acoustic test methods are discussed, and acoustic wave motion, impedance, and intensity are described. Wave propagation and signal absorption, and the velocity of sound are discussed.

Defect Identification through Partial Discharge Analysis on HVDC: Partial Discharge Fingerprinting
2021The electricity grid spanning hundreds of thousands of kms is one of the most complex man-made network built in human history. Today, after a century of growth, progress and innovation, the electricity grid is in the process of undergoing another landmark shift in its operation.

Partial discharges and their measurement
2004The study of partial discharges is not an academic pursuit. It is driven by a very practical desire, a desire to understand a phenomenon which can be utilised to infer the level of integrity within the insulation systems of high voltage plant and which, in itself, constitutes a serious stress degradation mechanism. The role of partial discharge studies

Partial discharges in polymer insulation
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1982, 1982Evolving power conditioning system requirements in many technological areas will place severe demands upon long-lived, repetitive, pulse-power components. A major pacing system component in this high reliability, repetitive pulse-power technology is the energy storage capacitor [1].

Partial Discharge Localization Inside Transformer Windings via Fiber-Optic Acoustic Sensor Array
IEEE Transactions on Power Delivery, 2019Partial discharge (PD) is the main sign of the insulation deterioration; therefore, the online PD localization of the power transformers can provide the equipment degradation characteristics and has great value for the power grid.
