| Abstract: | Substation 35 kV distribution system is a system that neutral generally is not directly grounded,there is voltage imbalance in the operation . The article generated power system voltage imbalance from the voltage transformer, combined with the specific characteristics of 35 kV line, highlighted the bus voltage imbalance and its causes during the operation in the field caused by the line voltage transformer, and then we calculated and analyzed the events with actual conditions. Finally, the improvements measures are given for the results. |
