Answer / rabi
As the rate of change of flux that links with primary and
secondary is same. so induced emf by per unit turn is same
for both secondary and primary.

Answer / gtmanikandan
voltage induced per turns(emf/turn)
=system rated voltage /total number of truns for both
primary or secondary
according to above formule ,both primary and secondry
indce voltage per turn equal

Answer / saranya
E2/E1=N2/N1(Voltage transformation ratio)
E2/N2=E2/N1.so the emf per turn is same.

Answer / 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= f*Fimax*Sin(wt-pi/2); if flux, Fi=Fimax*sinwt.

Answer / rizwan ansari
current density is estimated 1000-3000 per square inch but
for middle type operations it is taken 2000.
now: take the b0bn size 1*1*1 inches and supply volts are
200 then formula for primary turns is turns*volt=8*200=1600
if want output 6v,12v for this multiply
turn*volt=8*6=48 for 6 volts
turn*volt=8*12=96 for 12volts respectively.

For a 500 MVA 400/220/33KV transformer following data given HV power = 500 MVA IV power = 500 MVA LV power = 5 MVA If input power is 500 MVA then how output power is (500+5)MVA. Can anyone help
Three set (each phase contain 2 cable of 400 mmsq CU XLPE AWA) of single core cables are connected to 11 KV motor of 14 MW & the switch gear supplay is taken from 11kv feeder & this supplay taken from 275 KV substation. Problem is one pair cable(L3- 2 cable ) getting very hot & gland melted and damaged in switch gear side. the other two cable haven't any more hot(ambient temp only & L3 haveing 95- 100 Degree C. The same problem happened in 275 KV substation switch gear side also where the supply taken for 11 kv switch gear. But here L2 phese cable had problem. Why it is happening like this?. The cable having temperature different at different location from gland side inthe case of 11KV feeder of 275 kv substation. why ?
