Excellant brother...

Hi, at 19:36, if 90% loading is allowed, means 0.9 x rating = 1200 kVA which gives rating as 1333.33 kVA. I didn't understand why you used 10% of 1200 to calculate that? To me my approach seems more straightforward. But then our results differ. Please clarify, thanks!

Good presentation brother

In primary side we are having 2voltages like 11kV and 33kV which one we have choose

[@electricalconcept32]

Your power supply authority which voltage level provided that voltage has to be chosen

[@vanithareddy446]

And how to deside steps like 7steps 5steps tap changing in trafo side pls let me know
