if there is three phase power system we calculate power kw= sqrt(3)*V*I*CosØ so what is formula for two phase system?
Dear Mr. Jatin333
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 “
