3Phase Panels with 19 Circuits to monitor

[scar4731]

I have three 3 phase panels that contain 19 circuits that I would like to monitor. The balanced two and three phase devices have one CT Sensor on only one leg whereas the unbalanced have a CT sensor on each leg. I am interested in knowing how much Wattage is being used by each of the 19 circuits and am not concerned about knowing the full usage of all three panels, so I figured I could use the 200A CT sensors just like I would the 50A Sensors. With the exemption of A, B, and C terminals (I still am not sure how to configure those in my YAML file, I have included the correct phase for each circuit. On a 220VAC single phase AC, one leg seems to be reading correctly, but the other is measuring 0. Why would that be? Additionally devices that are on seem to be pulling very low wattage (i.e. 3.5W for a 5 ton package unit with a multiplier of 3). What should I change in the YAML file to make terminals A,B,and C simply CT sensors and not use their data as a multiplier (if I can)?

exemption of A, B, and C terminals

Do you mean the phases: section? Configuring that incorrectly would cause problems that sound like what you're experiencing, where every clamp on a certain phase is reading 0.

Are the voltage readings accurate?

Phase A: 112V, 59.8Hz
Phase B: 126.6V, 240deg (PH Angle)
Phase C: 113V, 125 deg (PH Angle)

But terminals A, B, and C are attached to circuits connected to Black, Red, and Blue (L1, L2, and L3) respectively.

My Phases section looks like this:

All three legs have circuits attached that only show 0. Additionally the Power for A, B, and C is at 0 as well. Do the A, B, and C CT sensors have to be attached to the incoming L1, L2, and L3?

Appreciate the extra data--this makes sense & looks right so far. I think I'm understanding the problem a little better--it kinda sounds like maybe the Vue is expecting a positive current reading (for the current to travel in the direction of the arrow on the clamp), but there's actually a negative reading.

What do you see when you replace *pos on the circuits with this issue with *invert? Does the data look about right?

[scar4731]

Yes, works. Before I received your message I had cleared all filters, but the data was very noisy. Thank you for your help!
