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 “
