In a three phase system star connection line voltage is root of three. So 2000kv multiply with root of three.
In delta connection: Line current = Square root of 3 multiplied to Phase current while Line voltage = Phase voltage.
In delta connection: Line current = Square root of 3 multiplied to Phase current while Line voltage = Phase voltage.

vl = root three*vph.
= 1.73*2kv.
= 1.73*2000.
= 3460 volt.
= 1.73*2kv.
= 1.73*2000.
= 3460 volt.

In a three phase system star connection line voltage is root of three so 2000kv multiply with root of three. It is right answer.

VL = 1.732*VPH.
VL = 1.732*2000.
VL = 3464.
VL = 1.732*2000.
VL = 3464.

Line voltage = root three phase voltage, so 1.732*2000 = and is 3464.

VL= ROOT 3 INTO VP.
VP = 2KV = 2000V.
ROOT3 = 1.732.
VL = 1.732 [2000] = 3464.
VP = 2KV = 2000V.
ROOT3 = 1.732.
VL = 1.732 [2000] = 3464.

VL is equal to the Vph.
VL = root3*Vph.
= 1.732*2000.
= 3464.1016V.
VL = root3*Vph.
= 1.732*2000.
= 3464.1016V.

In wye connection: Line voltage = square root of 3 multiplied to Phase voltage while Line current = Phase current
In delta connection: Line current = square root of 3 multiplied to Phase current while Line voltage = Phase voltage
In delta connection: Line current = square root of 3 multiplied to Phase current while Line voltage = Phase voltage
