Power factor on Delta load

Thread Summary

The user is measuring power factor in a delta connection using the ADE9000 and observes that individual phase powers are not meaningful. The final answer confirms that the power factor should be calculated using the total active power (P_A + P_C) divided by the total apparent power (A + C), and Phase B power is not useful in Delta mode. The power factor of 0.87 for the total system is correct.

Hi!
I'm on a delta connection measuring power factor with the ADE9000.

My setup has a 220/127 source and three 40.33 Ohms load on each phase

The datasheet(UG-1098) says this
"In a Blondel compliant 3-wire delta meter, only the overall power consumed by the system is meaningful; the individual phase powers are
not meaningful because a line current is multiplied by a line to line voltage
To obtain the overall power consumed by the system (active, reactive,
and apparent), add the contribution from Phase A and Phase C."

and indeed when measuring active power I get
P_A:1802.82   --   P_B: 5.75  --  P_C: 1812.86

PA+PC = 3615.68 (close to the 3600W I expected)


this also affects power factor as I get 0.87 on phases A and B (which in my understanding is right for a delta connection if I measure Line current and line to line voltage)

Is there any way or configuration i can try to get a power factor of 1 directly from the ADE9000? Or really the only way of getting power factor on this setup is by doing P/S?

what about the true power factor on each phase?
