Innovative way of Understanding Test Results Obtained by DGA Test of power Transformers based on iEEE & iEC Standards Dr. Arora Rajesh Kumar Delhi Transco Limited Online published on 6 February, 2020. Abstract The transformer, being a key element in the transmission and distribution of electrical energy, improving its reliability is of utmost importance. System abnormalities, loading, switching and ambient condition normally contributes towards accelerated aging and sudden failure. Hence, it is, all the more essential, to employ continuous monitoring techniques and on-site diagnostics followed by quality maintenance for having trouble-free and reliable operation with minimum outages. This paper provides an overview of the latest condition monitoring, diagnosis technologies and detail of DGA testing & its interpretation using innovative method as per IEEE and IEC standards. Top Keywords Dissolved Gases Analysis (DGA), Power Transformer, Transformer Oil Sampling, TDCG (Total Dissolved Combustible Gases). Top |
