CONSIDER A 415V/200V STEP DOWN TRANSFORMER.CAN WE USE USE
IT AS STEP UP TRANSFORMER BY GIVING 200V IN SECONDARY AND
TAKING OUTPUT FROM PRIMARY?

Answer Posted / ashokreddyreguri

The given t/f is 415 v/200 v(h.v/l.v).
If the supply is given to 415 v side and o/p is taken from
200v side then it is step down t/f.
If the supply is given to 200 v side and o/p is taken from
415 v side then it is step up t/f.
We can use the same t/f tor step up and step down operations
