3 Phase Power

[obsessed]

I currently have the Full Version of EPS.  I am trying to measure 3 Phase Power and it looks to me that the values calculated out of Power Values.vi does not actually calculate 3 phase total power, but rather the 3 individual phase powers ignoring the fact that they are in a 3 phase configuration.

Basically I feel like it is missing a SQRT(3) to account for a DELTA or WYE configuration.

Has anyone else noticed this?  Am I doing something wrong?

Hi,

There is the "total power values" output interface on the Power Values.vi. It indicates the total power of the 3 phases.

 On the front panel of the EPS examples, you should choose the correct wiring method. And in the LabVIEW Help, you can find the description about the wiring on the following path: Toolkits -> Electrical Power Toolkit -> Electrical Power Concepts -> Electrical Power Signals -> Connections and Wiring -> Wiring.

You can use the D to Y Convert.vi or Y to D Convert.vi to make the conversion.

So you don't need to convert the D and Y by sqrt(3).

Thanks!
