Phase Current to Line Current Conversion Calculator

Phase current to line current calculator:

Enter the phase current then press calculates button to get the line current.

Enter Phase Current: A
Result – Line Current: A

Phase current to line current formula:

Line current is I(L) in Amps is equal to root 3 times of the phase current I(P) in amps.

I(L) = I(P) x 1.732


What is the line voltage of the delta connected system whose phase current is 500 Amps?

Apply our formula

I(L) = 500 x 1.732 = 866 Amps.

I(L) = 866 Amps.


If the system is star connected, then

I(P) = I(L)

Line current in amps is equal to phase current in amps.
