Answer / srinivasa rao talasila
Primary current=2500000/1.732*33000
=43.74A
Secondary current is =2500000/1.732*433
=3333A

Answer / pillay
sec 433volts of a 3 phase 2500 KVA TXformer will be
2500,000 / 1.72 / 433 = 3356 amps.

Answer / raj
input power= output power => transformer do's.
depends on ur load they will design.

Answer / gopal
HT CURRENT
I=LOAD/VOLTAGE
I=2500X1000/33*1000=75.75A
LT CURRENT
I=LOAD/1.732*433
I=2500*1000/1.732*433=3333A
OR USE SIMPLE FORMULA
1=LOAD X 1.4

Answer / gnanendra
Hey.. It is very important to mention whether it is 1-phase or 3-phase.. See any text book.. If rating given means in that it will be definitely mentioned..

Answer / s bharath
p=1.732*v*i*0.8
2500=1.732*433*i*0.8
i=2500*1000/1.732*433*0.8
i=4.16kA
| Is This Answer Correct ? | 6 Yes | 8 No |
Answer / kaami
power in = power out
v*i = v*i=2500kVA
on input side
33kv*i=2500kv
i=2500/33=75.75amps
on output side
v*i=2500kva
433v*i=2500Kva
i=2500/433=5.7ka
so it is designed for 5.7KA on secondary side

Answer / rafeek
p=3^1/3*vicos$
=3^1/3*415*i*0.8
p = 575i
p=250*0.8=200kw
200*1000=575i
i=347.82
i=347.82*1.2=417.39
i-~=400amps
