What is the formula for power in 2 phase systems? A two phase system is a centered tapped transformer. Therefore the power is the sum of the phase voltages multiplied by the line current = 2 x Vphase x Iphase.
To calculate the power value accordingly to : Voltage, Current, and Power Fcator, we have the following formula :
– For 3 Phases plus or withour neutral :
P = sqrt(3) x U x I x Cos Ø
– For 2 Phases :
P = U x I x Cos Ø
– For 1 Phase + Neutral :
P = V x I X Cos Ø
where :
U : Voltage between 2 pahses in ” Volt “
I : Current line in ” Amp “
V : Voltage between phase & neutral in ” Volt “

– For 2 Phases :
P = Vph*I*Cos Ø
– For 1 Phase + Neutral :
P = V*I*Cos Ø

Vph : Voltage between 2 pahses in ” Volt “
I : Current line in ” Amp “
V : Voltage between phase & neutral in
