Yes, you can run parallel wires from the same phase either through a single CT or you can run them through 2 CTs connected to the same inputs on the Omnimeter. Make sure that if you have say a 400 amp system that you use 2 400 amp CTs with your meter set to a 400 amp CT ratio. Ideally I would solder the CT wires together and then connect them to the meter.First, is it possible to use two current transformers on a single input of an omnimeter to read the total of the two lines?
You will not have an accurate Total kWh if you do this. If you use the Omnimeter Pulse v.4, you will get accurate kWh on Each Line. With this you can have kWh and watts for each of the three 2 wire systems.Next, can I use one omnimeter to monitor three lines on the same phase? or are the three inputs strictly for three phase power? If so, could I monitor three separate 220v 2 wire single phase sources?
We use sqlite databases. I would not know how to tell you the format of the database itself, but if you want to take a look, you can make a copy of your Dash DB then open it up and see what is in there. To find the DB on a Mac I hold the "option key" when opening the EKM Dash.and last, for an installation with no internet, If I were to write a program to log data on my Raspberry Pi, Is the database format available for your dash software?
