Analysis of Harmonic Current in Traction Rectifier Transformer with Axial Double Split Structure and 12 Impulse

Harmonic current in windings of traction rectifier transformer with axial split structure is analyzed and conditions for restraining the remaining component of uncharacteristic harmonic produced by unbalanced load are presented. The harmonic current in the windings on the line side under practical running condition is analyzed. The indispensable technical requirements for restraining it in traction rectifier transformer are introduced.
