FIELD: electrical engineering.
SUBSTANCE: invention can be used to determine the three components of losses in the magnetic core of a transformer. The technical result from the use of the invention is the ability to determine the losses for hysteresis, for eddy currents and anomalous losses in the transformer based on three measurements and calculation. The method for determining magnetic losses in a transformer includes measuring losses in steel by an open-circuit test at rated frequency, at rated and two reduced voltages and calculating losses by three measured values of losses in steel and two coefficients of the ratio of two reduced voltages to the rated voltage.
EFFECT: ability to determine the losses for hysteresis, for eddy currents and anomalous losses in the transformer based on three measurements and calculation.
