Answer Posted / pramit dutta
Transformer is transfer energy from primary to secondary.
So it needs changing flux in its core so that the flux can cut
across windings and induced voltage and current. We know,
e=-N da/dt ,where a is flux in core. So if pulsating dc id applied to its primary then the lines of flux will be constant. So e will be 0. So energy can't be transfered.

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
