Phase voltage to line voltage calculator:
Enter the phase voltage then press the calculate button to get the line voltage.
Line voltage is V(L-L) in volts equal to root 3 times of the phase voltage V(L-N) in volts.
V(L-L) = V(L-N) x 1.732
Example: What is the line voltage of the delta connected system whose phase voltage is 240 Volts.
Apply our formula
V(L-L) = 240 x 1.732 = 415 Volts.
V(L-L) = 415 Volts.
If the system is delta connected, then
V(L-N) = V(L-L)
Line voltage in volts is equal to Line to neutral voltage in volts
