Answer / viswakumar
% impedance is the voltage required to circulte full load
current in both HV and LV windings when the terminals of
the LV winding is shorted. This is just the SC test done
in the college lab.
For example if 5 % of 11KV circultes full load current in
the both 11KV side and 415 V side of a 11KV/415 volt
transformer then the % impedance of the transformer is 5%

Answer / abdulsubur
1000kva trasformer
1000/root3*.4=1445A=I flow in secondary current
400*5.75%=23
23/1400=.2 0hms

How to calculate earth wire load by formula
I am having a DG set.The 415 V from Generator is step up to 460 v and then the same is used for Induction furnace. before Step up, I am connecting LT load to my factory use. When Induction furnace is in service from DG, when i try to start a motor, the generator is tripped.Please tell me the reason.
