I want Primary side delta and Sec side Star connection transformer . but i have received Star - Star transformer ,shall i use the same transformer by giving the only 3 ph on Primary side without Neutral connection on the Starpoint.
5 11319Why current flows in nutral? As per theory there should be no current in 3 ph explain.
