English abstract:
The distribution of eddy currents in the core clamping parts and the tank
wall of power transformers is obviously different between measurements of
load losses and normal operational conditions. Thus, the calculation of
these losses shows the regions of possible hot-spot temperatures with
normal operational conditions. The presented analysis method uses 3D
nonlinear time-harmonic finite element analyses with a nested multigrid
solver. Consequently, the occurring short calculation times allow to take
into account for ambitious technical specifications and individual
customer demands.
