why dc power can not be used in transformer?

Answer Posted / booma

THE RESISTENCE IS VERY LESS IN TRANSFORMER INSTEAD WE GIVE SUPPLY DC THEN AC THE FOLLOWING HAPPENS DONE
BECAUSE OF HIGH I THE RESISTENCE SHOULD BE DAMAGED AND ALSO THE COILS SO THE PERFORMENCE OF THE TRANSFORMER WILL AFFECT THEN THE TRANSFORMER SHOULD BE AFFECTED

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
