in a 11 kv/440v transformer, what happen to the secondary voltages if any one phase of 11kv supply fails.
My guess, Mar, is that the secondary voltage drops and the current capacity decreases
man, Eng, where are ye
OP has not specified whether primary is star (wye) or delta, and likewise for secondary. Whichever, the answer is available in any electrical engineering textbook.
