Abstract:The paper presents the investigations carried out on a transformer for various simulated faults to obtain FRA data and study the applicability of various numerical techniques. The numerical parameters Viz., Min-Max ratio (MM), Mean Square Error (MSE), Maximum Absolute Difference (MABS), Absolute Sum of Logarithmic Error (ASLE), Standard Deviation (SD) and Correlation Coefficient (CC) computed in three different frequency bands are presented to aid the interpretation of SFRA data. Frequency responses among iden… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
