My 3-phase installation uses emontx 3 and 3x100A CT’s. My question is how do l set-up the correct process as an input to show the sum of the three phases? See the attached for my progress so far.
Hi,
Show us a screenshot of your Inputs page so we can see what processes you already have.
Here’s a screenshot of mine:
I’m guessing by what you have there that you just have your 4 inputs with a simple “log to feed” process. All of the work is going to happen on that Inputs page so that’s where you need to be focused
The majority of the “work” is done in my powerL3 input. Here’s the processes I use:
So that Logs L3 to an “Power-C” feed, then it adds the values of the “Power-A” and “Power-B” feeds (which have their own input processes as in the screenshot above) and then logs that to a “Total” feed (in my case called “W-TOU” for Watts - Time of Use" - I have another power feed that is not charged time of use so needed to differentiate)
I then take the total W-TOU and turn that into kWh and log that to another feed “kWh-TOU”
That should get you your total, you can get ever more complicated from there!
Hi
I applied your recommendations and things are working fine, many thanks. I was just unable to complete power 4 according to your settings as l need to know which processes to assign to the process list:
Log to feed
Power to kWh
+feed
Log to feed
Power to kWh
As requested l have attached my Inputs page.
By the way, is there a doc that describes the applications for the various processes?
Thanks
In my case, power4 is a 4th CT clamped around my controlled load power feed (unrelated to my 3-phase feed).
Assuming you only have 3 clamps, you’ll only have 3 power inputs and power 4 will always be 0, is that the case for you?
