Answer Posted / mrithun
The power factor of transformer is unity.
Since KW=KVA*cos(phi)
KW=KVA*1 (in case of transformer)
KW=KVA
So transformer is rated in KVA and not in KW.

5- What is the task (function) of the excitation and isolation transformers in power plant? 6- What is the task (function) of LCI (A), LCI (B) and LCI (COS) in power plant? : LCI (A) and LCI(B) are load commutating inverter for generator turbine starting. , LCI (COS) is load commutating inverter change over switch
A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
