Measures with 3-wire - Delta and unbalanced system with ADE7758

Hello everybody!


I have my power meter which is capable of measuring active energy and apparent energy. Normally, I tried to configure it for measure voltage and current through every phase load. But now I'm facing some problems, I have a triphasic system like the one showed in the image below.


In this system, I'm able to connect the power meter to measure loads voltage, but not phase current, only line current (I1, I2, I3). And also, the system is unbalanced.

I read the datasheet and found something about ANSI C12.10 but nothing more. Can I configure the ADE7758 to take the correct measure of active and apparent energy while connecting the current clamps to I1, I2 and I3 ???



Thanks for the help!
