Sakshi Singh,Mirza Mohd. Mohsin,Aejaz Masood 한국전기전자재료학회 2017 Transactions on Electrical and Electronic Material Vol.18 No.6
Breakdown of solid insulating materials in power equipment could result in undesired outages and replacements, and maybe due to an increase in electric stress on the material. Therefore, it is necessary to conduct a proper diagnosis of materialsbefore their practical use. In this work, a few inherent properties of different non-cellulosic insulating materials, such asNomex, Teflon, laminated Nomex, glass bonded mica, epoxy resin bonded mica paper, and epoxy resin bonded fiberglass,have been evaluated by performing non-destructive dielectric diagnostic measurements, and an attempt has been made tocorrelate these basic parameters to evaluate the breakdown strength (BDS). An equation has been proposed using a basictheory which defines the correlation between the BDS, dielectric constant, dissipation factor, sample thickness, and volumeresistivity. The results obtained from the equation are also compared with the experimental values. The suggested equationwill be helpful to predict the BDS of any non-cellulosic material without experimentation in the laboratory.
