Low-voltage short-circuit impedance measurement is basic subject in routine test. Comparing the short-circuit impedance value of transformers before and after short-current impact, to estimate winding distortion degree according to variable value. The changes of transformer impedance should not be over 2%.
LV short circuit impedance test is the most direct way to check winding distortion when the transformers are impacted by short circuit current or mechanic shocked by transportation and installation. It is useful to judge if the transformers can be put into operation.
