Abstract :
Stray losses outside of windings are a subject of numerous different analyses in the power transformer production industry. The purpose of this paper is to illustrate an approach that combines 3D finite element static magnetic field calculation and nonlinear mathematical programming in a single method derived to increase accuracy of stray losses estimation.
