Analysis of Negative Sequence of Traction Transformer with V/v Wiring

Connection principle and characteristic is briefly introduced of the V/v Connection traction transformer. The negative sequence currents under different loads are calculated and analyzed, and the rules of the current unbalance degree at the high voltage side are described in the form of curves. Combine to actually measure datum in traction substation with the V/v connection traction transformer, analyzed its negative sequence voltage and its voltage unbalance degree, and the rules of current unbalance degre...
