Transformers provide some interesting features in setting up sequence networks.The first of these arises from the fact that wye-delta or delta-wye transformer connections produce phase shifts from primary to secondary.Depending on connection,this phase shift may be either plus or minus 30° from primary to secondary for positive sequence voltages and currents.It is straightforward to
show that negative sequence shifts in the opposite direction from positive.
Thus if the connection advances positive sequence across the transformer,it retards negative sequence.This does not turn out to affect the setting up of sequence networks,but does affect the re-const ruction of phase currents and voltages

变压器提供设立顺序网络的一些有趣的功能.其中第一个来自一个事实,即星形增量或delta- Y形连接变压器由初级阶段生产转移到次要的.在连接的不同,这可能是相移加上或减去30 °从小学至中学的正序电压和电流.它可以直接
表明,在从正对面的负序方向转变.
因此,如果通过变压器连接的进步正序,负序它阻碍.这并没有显示出影响网络的设置序列,但并不影响相电流和电压重新const的乱子
