Frequency dielectric influence of imaginary admittance on oil-paper insulation system-a case study
Yang, Xu, Nielsen, Shawn, & Ledwich, Gerard (2013) Frequency dielectric influence of imaginary admittance on oil-paper insulation system-a case study. In Proceedings of the 2013 Australasian Universities Power Engineering Conference (AUPEC), IEEE, Hobart, Tasmania, Australia, pp. 1-6.
Frequency Domain Spectroscopy (FDS) is used to assess the insulation condition of oil-paper power transformers. Dissipation factor is one of the conventional indicators to analyze insulation ageing status. In this paper, the imaginary admittance of the transformers insulation, after removal of the geometric capacitance, is proposed as an alternative indicator to assist in the interpretation of ageing status. Ageing effects on the imaginary admittance are investigated both through simulation results and experimental results.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
