EDDY CURRENT LOSSES IN TRANSFORMER LOW VOLTAGE FOIL COILS

Vladimír Zúbek

   The paper deals with eddy current losses in transformer low voltage foil coils, where the measured value of the load loss is usually much higher than the one computed by standard procedures. The work brings results explaining analytically the source of the discussed loss and formulas, and a procedure allowing to get results of sufficient preciseness.
