Accurate partial discharge classification from acoustic emission signals
Harbaji, Mustafa; El-Hag, Ayman; Shaban, Khaled (2013 , Conference Paper)Accurate partial discharge (PD) classification provides significant information to asses power transformers' insulation condition. The work presented in this paper aims to improve classification from acoustic emission ... -
Cost effective assessment of transformers using machine learning approach
Benhmed, Kamel; Shaban, Khaled Bashir; El-Hag, Ayman ( IEEE Computer Society , 2014 , Conference Paper)Furan content in transformer oil is highly correlated with the transformer insulation paper aging. In this paper, the ranges of furan content in power transformer is predicted using measurements of transformer oil tests ... -
Feature selection for effective health index diagnoses of power transformers
Benhmed, Kamel; Mooman, Abdelniser; Younes, Abdunnaser; Shaban, Khaled; El-Hag, Ayman ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Article)This letter investigates an approach based on feature selection and classification techniques to reduce assessment complexities of power transformers. This approach decreases the number of features by extracting the most ... -
Predicting transformers oil parameters
Shaban, Khaled; El-Hag, Ayman; Matveev, Andrei ( IEEE , 2009 , Conference Paper)In this paper different configurations of artificial neural networks are applied to predict various transformers oil parameters. The prediction is performed through modeling the relationship between the transformer insulation ... -
