Answer Posted / santanu das
Since the same amount of flux links primary as well as
secondary windings, the induced emf per turn is same for
primary and secondary windings. That's why, per turn
induced emf:
E1/N1=E2/N2= w*Fimax*Sin(wt-pi/2); if flux, Fi=Fimax*sinwt.

WHAT DO YOU MEAN THE DIFFERENT TYPE OF CURVES OF RELAY LIKE STANDARD INVERSE, VARY INVERSE, NORMAL INVERSE, LONG INVERSE ETC....
3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
