Abstract
Along with the requirement to significantly increase the voltage and the capacity of the power transmission and transformation equipment, to the highest level in the history of the world, came the requirement for much more efficient computer-aided analysis and design techniques, involving a more accurate modeling of the material properties. In other words, when simulating a low voltage/capacity equipment, some errors in the approximations, used in the numerical techniques, are not as critical, but must be considered for the case of the high voltage and large capacity equipment.

New Challenges in Electromagnetic Analysis and DesignAlong with the requirement to significantly increase the voltage and the capacity of the power transmission and transformation equipment, to the highest level in the history of the world, came the requirement for much more efficient computer-aided analysis and design techniques, involving a more accurate modeling of the material properties
It should be noted that the research and development of advanced material modeling techniques, at the present, is not fully integrated in the computer aided simulations
The accurate computation of magnetic losses in large electromagnetic devices, possibly under extreme excitations, has become increasingly important and remains to be very challenging, requiring an efficient numerical field solution and a magnetic material model that simulates the true material behavior, as experienced when the equipment is under operating conditions; the latter requirement necessitates a validation procedure that is based on the characteristics of the equipment itself
