Abstract :
This paper presents the optimal location and geometry of a magnetic shunt in a distribution power transformer. To speed up the problem solution, it is divided into two cases; firstly, an axisymmetric FE model is used to find its vertical placement and secondly, a 3D magnetodynamic FE model is employed to find the remaining dimensions. A genetic algorithm and the Powell method are used to find a global minimum
