The windings of a Q kVA, V1 / V2 volt, three-phase, Delta connected, core type transformer are reconnected to work as a single phase transformer. The maximum voltage and the power ratings of the new configuration are
-
- 3V1 / 3V2, 3Q
- V1 / V2, 3Q
- √3V1 / √3V2, 2Q
- 2V1 / 2V2, 2Q/3
Correct Option: D
Current will be same but voltage become 2V (V/2,V/2,V) due t o maximum flux density constraint.
