All electrical devices that supply power are usually rated in kVA. This includes transformers, UPS's.

Hai friends, transformer ratings is always measured in KVA.

kva:v*i - (1000*2*8) - 16000 - 16kva.

Actualyy rating of a transformer is in Kilo Volt ie KV
1KV = 1000 Volt
Therefore divided by 1000

kVA rating = EI. Here 8 amp and secondary voltage are given then multiply both then we
get 16.

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

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

KVA=V1*i1=V2*i2.

Therefore here, V2=2KV, i2=8Amp.

Then, KVA=V2*i2.

KVA=2*8;

KVA=16.

Transformer rating is in KVA(Apparent Power).

Apparent power = V*I = 2KV*8A = 16 KVA.

If a 1000kva 200hz transformer is operating at 50hz, its kVA rating is? please solve.

What is the main advantage of parallel operation of two single phase transformers?
