Direction of Power #16

Closed xianrecords2015 closed 4 years ago

This is more a question. The Irms and Vrms seems to always be positive no matter what the direction of the CT is and no matter what the direction of the current/voltage is.

I have a couple of CT on a Solar line and the Grid that is sometimes fed by Solar and then becomes negative Power.

How can I find out the direction of the power with the CS5490 ?

Thank you,

Christian

I guess I found my answer. The Active Power will provide the direction of Power (Neg/Pos)
