If we wana take answer in MVA we will convert voltage from KVA to MVA by Dividing it by 1000

The transformer KVA rating is found out from the formula
Full load secondary current(I2) = KVA/secondary voltage(V2)
From this formula, KVA =I2*V2 = 8*2 = 16

We know that t/f raiting is KVA
So,
kva=kilo volt*A(amp..)
2*8=16KVA

2000*8\1000=16

KVA = V * A /1000 The raiting of transformer is Kilo Volt Ampeer so that it is divided by 1000.

JOGI said:   1 decade ago
KVA = V * A/1000
The rating of transformer is Kilo Volt Ampere . So that it is dvided by 1000. 2KV= 2*1000=2000 SO . 2000*8=16000/1000=16KVA . This is the ans for above problem

It's simple v2*i2=2kv*8
=16kv

Sudhandiran K said really well nice explaination........

p=vi
p=kva
v=2kv=2*1000v
i=8a
p=8*2*1000=16000va
p=16kva

Yeah..

8A*2KV=16 KVA
