Journal ArticleDOI
Investigations on leakage current and phase angle characteristics of porcelain and polymeric insulator under contaminated conditions
TL;DR: In this article, the analysis of leakage current and phase angle characteristics of porcelain and silicone rubber insulator was carried out in order to develop a better diagnostic tool to identify the pollution severity of outdoor insulators.
Journal ArticleDOI
Analysis of partial discharge characteristics of natural esters as dielectric fluid for electric power apparatus applications
TL;DR: In this article, the partial discharge characteristics of natural esters as a dielectric fluid for power transformer and other electric power apparatus insulation applications are analyzed using time and frequency domain analysis at both needle-plane and rod-plane electrode configurations.
Journal ArticleDOI
Inferring ceramic insulator pollution by an innovative approach resorting to PD detection
TL;DR: In this paper, a technique for outdoor ceramic insulator pollution assessment based on partial discharge detection and analysis is presented, which highlights the mechanisms bringing insulators to flashover (dry band arc activity) and is well suited to predict increasing pollution and imminent flashover.
Journal ArticleDOI
Tracking and Erosion Resistance Performance Investigation on Nano-sized SiO 2 Filled Silicone Rubber for Outdoor Insulation Applications
TL;DR: In this paper, the tracking and erosion resistance characteristics of nano-sized SiO 2 1 /2 filled virgin and aged SIR materials under AC voltage with ammonium chloride as a contaminant as per IEC-60587 test procedures were discussed.
Journal ArticleDOI
Partial discharge detection as a tool to infer pollution severity of polymeric insulators
TL;DR: In this article, the analysis of partial discharge characteristics of silicone rubber insulators with the aim of developing a better diagnostic tool to identify the pollution severity of outdoor insulators is presented.
