Answer / lokeshraj

There are two types of transformer...
1- Measuring T/F 2- Transmission or power T/F
further measuring T/F can be classified in CT and PT.
and transmission t/f can be classified in Step u and sped
down...

Answer / mahesh katakdhond

step up and step down

Answer / satish

There are many categories for types like:
1. core and shell type
2. power and distribution
3. step up and step down
4. oil filled and dry type

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 ?
