Voltage Ratio : 11000/440= 25, 33000/440= 75
So, current in primary will in 11KV= 4 Amps and in 33KV= 1.333 Amps

Answer / saraz06a0222

If KVA is known then these are the formulas

Current in LT side
=KVA *1000/1.732*LT VOLTAGE*COSQ


Current in HT side
= KVA *1000/1.732*HT VOLTAGE*COSQ

What is C.T, why it is used and what care should be taken for that while connecting?
