Tailoring insulation surface conductivity for surface partial discharge mitigation
TL;DR: In this paper, a surface coating with a conductivity ranging from 10−13 to 10−10 S is developed to regulate the surface charge migration in the vicinity of the triple junction and to suppress effectively the surface PD activity.

Electrical degradation and breakdown in polymers
L.A. Dissado,John C. Fothergill +1 more
TL;DR: In this paper, the physical and chemical structure of polymers and their breakdown are discussed, along with the stochastic nature of break-down from empirical and modelling viewpoints, and practical implications and strategies for engineers.
Journal ArticleDOI
A generalized approach to partial discharge modeling
TL;DR: In this paper, a generalized partial discharge (PD) model is proposed to derive approximate relations between defect characteristics, insulation design parameters and test conditions on one side, and measurable PD characteristics on the other.

Digital detection and fuzzy classification of partial discharge signals
TL;DR: In this article, a fuzzy classifier is used for the analysis of the acquired PD-pulse shape signals, and the result of the fuzzy classification is a cluster of signals homogeneous in terms of stochastic features of PD pulses.
