I have an HVAC unit and I know the phase 1 current, phase 2 current and phase 3 current. I know the voltage of the unit, from this, how can I calculate the power used by the entire unit?
Further information, does the HVAC unit have 3 separate voltages for 3 phase? I know for example, the one on my roof is 230 volts and it is 3 phase. Does that mean that I can use a voltage of 230 for calculating the power of each of the phases?
