求翻译：空载试验可以求得变比K、空载损耗P0、空载电流I0以及励磁阻抗Zm。是什么意思？

No-load test can be obtained ratio K, no-load loss P0, no-load current I0 and the excitation impedance Zm.

unladen pilot can seek change than K P depletion, empty I 0 and 0, no load current excitation impedance Zm.

The transformer idling electric current is refers primarily meets the rated voltage, the secondary complete idling measures primary electric current.This electric current and the coil in voltage product loses for the idling, also is refers to the transformer the ferrite core loss.Of it is the ferrit

No-load test can find than k, no-load loss P0, excitation impedance of no-load current I0 and Zm.
