In a 3 phase circuit,
The voltage between any phase line and the neutral point is called the phase voltage.
The voltage between any of the two phase line is called the line voltage.
The Line voltage = √3 x Phase voltage = 1.73 x Vph.
That is if the line voltage of a 3 phase supply is 400V, then the phase voltage will be around 400/1.73 = 231V.
11KV, 220KV are line voltages, the voltage between lines RY, RB, YB.
Phase voltage of 11kV and 220K are 11KV/1.73 = 6.35kv and 220kv /1.73 = 127.16kv, phase voltage is the potential between line R or Y or B and neutral.
Phase voltage = line voltage / 1.73
400V is just an example if the line voltage is 400V then phase voltage is 231v.

Can you explain more about 11kv 220kv etc…y the multiple of 11?….how to find the phase voltage…how it is 400v?please explain simply

phase to phase voltage in a 3 phase line is √3 * Eph.
Phase-Phase voltage, VRY=VYB=VRB = 1.73 x Vph (1.73 = square root of 3)
