In star connected systems,
Line voltage is √3 phase voltage .
i.e. = 2000 * √3 .
Hence 3464 is the answer.
Line voltage is √3 phase voltage .
i.e. = 2000 * √3 .
Hence 3464 is the answer.

Phase voltage = 2000v.
So,line voltage = root3 * 2000 volt,
= 3464volt.
So,line voltage = root3 * 2000 volt,
= 3464volt.

In star connection line current = phase current,
Line voltage = 1/3 phase voltage.
And in delta connection line voltage = phase voltage,
Line current = root 3 phase voltage.
So, how is the answer 'd' correct?
By this star connection, the answer is 'c'. It's the right answer.

2kv = vph root three * vph.
1.73 * 2000.
= 3460 VOLT.
1.73 * 2000.
= 3460 VOLT.
