...Nasser Kianimehr; Hamed Zeinoddini-Meymand; Farhad Shahnia Purpose Power transformers are vital components of an electrical network. A defective transformer can cause instability and blackouts in parts of the network. An accurate classification of different transformer faults results...

...[ 2 ] proposed, instead of abstract single‐phase electromagnetic device, to pass directly to the complex 3‐D, 3‐phase, thermally and ferromagnetically non‐linear model represented by contemporary large power transformers, for which many measurement results were published by M. Kazmierski [ 3...

...Krste Najdenkoski; Dionis Manov This paper aims to determine the electromagnetic forces acting in a power transformer, when a current corresponding to the first peak of a three‐phase circuit flows in the windings. The finite element method for the evaluation of the field’s values is applied...

...Jawad Faiz; Mansour Ojaghi In this paper, different shapes of the boundary surfaces within the power transformers are reviewed. The surface charge distribution function on the two surface elements, which have the majority of usage, are recognized and the resultant potential and electric field...
