options for connecting an intelligent meter to account for the entire electric current of an industrial facility with a supply cable line cross section of 3 * 150 mm2, what options for organizing metering for a system at Victron Energy? and which meter to choose for these tasks?
If you check this sheet of Victron, you can see that it's possible with certain panel meters, and when using current transformers.
Based on the above table, it is not clear which meters support transformer connection, it is planned to install current transformers 250/5A with an accuracy class of 0.5S. I didn’t find a transformer switching circuit with grounding of the secondary winding for these types of meters, if it’s possible to describe this moment in more detail, Thank you.
According the table, you can meassure >65A tree fase with the Carlo Gavazzi EM24, EM330 EM530, or ABB B24 meters. Did you check their specs separately?
They all have current transformer inputs and work with RS-485 dataprotocol to input your Victron devices.
I would choose the ABB meter becasue I find their quality better than Italian hardware.
