Whats the power in a 2 phase system?

Click For Summary
SUMMARY

The discussion centers on calculating power in a two-phase system, specifically in the context of an old machine operating on a three-phase supply with one phase disconnected. The key takeaway is that the total power in a two-phase circuit is the sum of the power from each individual phase. The user confirmed their understanding of the voltage, current, and power factor for both phases, leading to the conclusion that no additional calculations are necessary beyond summing the two phases' power outputs.

PREREQUISITES
  • Understanding of two-phase power systems
  • Knowledge of voltage, current, and power factor calculations
  • Familiarity with three-phase electrical supply systems
  • Basic electrical engineering principles
NEXT STEPS
  • Research two-phase power calculations in electrical engineering
  • Explore the differences between single-phase, two-phase, and three-phase systems
  • Learn about power factor correction techniques in two-phase systems
  • Study the implications of operating machinery on a two-phase supply
USEFUL FOR

Electrical engineers, technicians working with industrial machinery, and anyone involved in the design or maintenance of two-phase power systems.

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.
