Wavelet Kernel-Based Convolutional Neural Network for Localization of Partial Discharge Sources Within a Power Apparatus
Biswarup Ganguly,Sayanti Chaudhuri,Subrata Biswas,Debangshu Dey,Sugata Munshi,Biswendu Chatterjee,Sovan Dalai,Sivaji Chakravorti +7 more
TL;DR: A new convolutional neural network (CNN) topology using wavelet kernels to detect and discriminate single or multiple partial discharge locations in high voltage power apparatus with increased accuracy is presented.
Journal ArticleDOI
A modified Maxwell model for characterization of relaxation processes within insulation system having non-uniform aging due to temperature gradient
Arijit Baral,Sivaji Chakravorti +1 more
TL;DR: In this article, the authors proposed a modification of the classic Maxwell circuit, which is also composed of a number of parallel branches, but unlike the former, the proposed model considers each of the parallel branches to be composed of not just one but a many exponential functions.
Journal ArticleDOI
Improved tribological behavior of lubricating oil dispersed with hybrid nanoparticles of functionalized carbon spheres and graphene nano platelets
TL;DR: In this article, a novel synthesis method of Functionalized Carbon Spheres (FCS) coated with Graphene nanoplatelets (GNP) using a simple sonication technique is reported.
Journal ArticleDOI
Prediction of moisture present in cellulosic part of power transformer insulation using transfer function of modified debye model
Arijit Baral,Sivaji Chakravorti +1 more
TL;DR: In this article, the Modified Debye Model (MDM) is used to model non-uniform aging in cellulosic parts of oil-paper insulation in power transformers, and a parameter sensitive to insulation condition can be obtained from Transfer Function of MDM.
Journal ArticleDOI
Assessment of non-uniform aging of solid dielectric using system poles of a modified debye model for oil-paper insulation of transformers
Arijit Baral,Sivaji Chakravorti +1 more
TL;DR: In this article, a new model which considers the effect of temperature gradient on insulation properties is presented, which is capable of identifying such a model using PDC measurement data and it is also shown that use of conventional Debye model overestimates the pole values and the error increases with usage of the insulation.
