After cleaning the winding end, the leakage current becomes normal.
清除绕组端部污秽后，泄漏电流正常。
2
The winding deformation can result in the change of the parameters of leakage inductance during internal fault.
在内部故障的情况下，绕组变形将会导致漏电感参数发生变化；
3
A calculation method of deriving the reactance voltage of multi-oil ducts cylindric winding is introduced by using relative magnetic leakage method. And the calculation examples are given here.
