Thanks for your reply. Appreciate your time in looking at my question and concerns.
I'm quite new to transformers, only a handful year of experience. Figured maybe to point out that the HV & LV (Wye) are solidly grounded while Delta has neutral through zigzag transformer.
Also during...
Have done some reading for two winding transformers that energize from lower voltage side of power transformer (delta-Y) will see issues at lower voltage side, namely higher inrush current, high neutral current, have higher voltage drop. Some solutions were should energize with full winding by...
