Sažetak

Split-winding transformer is a one of the common transformer types with one low-voltage winding placed above
the other low-voltage winding and with the jointly high-voltage and regulation winding. The paper investigates circulating
currents that occur in high-voltage and regulation windings in case of nonsymmetric load. In addition, measurement of
circulating currents for a case of 240MVA, 220 kV transformer is presented along with a numerical calculation of circulating
currents and compared with the measurement.
