the lesson of electric machines and drivers -- transformer questions
question: the data of a single phase transformer are as following;
nominal primary voltage U1n= 230V
nominal secondary voltage U2m= 12V
line frequency f= 50 Hz
apparent power S=50 VA
loading resistor on secondary side is RL=3ohm
strayed field self induction coefficient in the simplified equivalent circuit Ls=Ls1+Ls2=0.06 H ?
winding ratio of transformer N1/N2 ?
nominal primary current I1n?
nominal secondary current I2n?
primary side transformed vaue of the loading resistor R'2?
