...Billel Allouane; Moustafa Sahnoune Chaouche; Samir Moulahoum Purpose This paper aims to present a novel analytical search space-narrowing optimization algorithm for accurately estimating the enhanced lumped mutually coupled ( ELMC ) equivalent model parameters of transformer windings. The ELMC...

...Abdallah Chanane; Houassine Hamza Purpose Accurate interpretation of frequency response analysis ( FRA ) data is crucial for power transformer windings. To address this challenge, this study suggests a new auto-synthesis method to derivate a high-frequency Equivalent Ladder Network Circuit Model...

... constraint handling technique and empirical relationship between the physical estimated parameters and their natural frequencies. Design/methodology/approach Frequency response analysis (FRA) is very significant for transformer winding diagnosis. Interpreting results of a transformer winding FRA is quite...

...Abdallah Chanane; Messaoud Belazzoug Purpose It is not a secret that the identification of the high-frequency ladder network model (LNM) parameters for the transformer winding is a crucial task. This paper aims to present the application of one of the latest swarm intelligence algorithms, namely...

...Carlos L. Antunes; Peyman Karimifard; G.B. Gharehpetian; Ahmad Javid Ghanizadeh; Stefan Tenbohlen Purpose The transfer function (TF) method is a reliable tool for the detection of the transformer winding deformation and displacement. One of the most important problems is the discrimination between...
