Whats the power in a 2 phase system?

Click For Summary
In a two-phase system, the total power is calculated as the sum of the power from each phase. The user seeks clarity on power calculations since traditional resources focus on single or three-phase systems. Knowing the voltage, current, and power factor for both phases is essential for accurate calculations. The discussion highlights the confusion surrounding two-phase power calculations. Understanding that the total power is simply the sum of the individual phase powers resolves this confusion.

I have an old machine that works across two phases of a 3 three phase supply.
the third phase is not connected.
All the books I consult show me how to calculate power in a single phase or three phase circuit but never in a two phase circiut.
I know the Voltage, Current and power factor of both phases
Is the total power the sum of the two phases or is there another calculation that is made ?

It's the sum of the power of each phase.

Thats great it was getting a little confusing.
 
I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
