FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used to determine the two components of losses in transformer steel. The method for determining magnetic losses in a transformer includes measuring losses in steel by the no-load test at rated frequency and low voltage and calculating losses for eddy currents and for hysteresis according to the passport value of no-load losses, the measured value of losses in steel and the ratio coefficient of reduced and rated voltage.
EFFECT: possibility of determining the losses for eddy currents and hysteresis in the transformer on the basis of simple measurement and calculation.
