Proceedings ArticleDOI
"Sub-hertz" dielectric spectroscopy
TL;DR: In this paper, two "sub-hertz" responses are considered that give insights into the insulating systems concerned, and the implications for nano-dielectrics are then briefly considered.
Proceedings ArticleDOI
Electrical breakdown strength characteristics of palm kernel oil ester-based dielectric fluids
TL;DR: In this article, natural ester fluids have been synthesized from crude palm kernel oil for consideration as an alternative to mineral oil based insulating fluid, and the breakdown test was carried out in accordance with ASTM 1816 test method using a bespoke test cell designed for small sample volume.
Journal ArticleDOI
Optimum estimators for the Weibull distribution from censored test data. Progressively-censored tests [breakdown statistics]
TL;DR: In this paper, the estimation of the parameters of the 2-parameter Weibull distribution from tests in which data has been progressively censored in different ways (50% censoring and two 30% censorship schemes).
Journal ArticleDOI

TL;DR: A novel protocol for PD measurement using AC voltages and VHF/UHF electromagnetic sensors, for quality control during routine tests on HVDC extruded joints, is proposed.
Proceedings ArticleDOI
Charge injection, electroluminescence, and ageing of an epoxy resin in high divergent fields
TL;DR: In this article, an epoxy resin (CY1301) under both uniform field and high divergent field conditions was studied under both high and low divergent conditions.
