-The article discusses the eddy current losses

generated in a transformer tank walls and other electrically

conductive construction parts. The losses are related to the

magnetic leakage fields. A time harmonic 3D finite element

method is used to compute the magnetic leakage field in the

case of nominal load condition of the power transformer. The

indirect measuring procedure based on the short circuit

method was carried out on many different power transformer

designs to validate the simulation results.--The　article　discusses　the　eddy　current　losses
