I want to monitor 3 Phase 380V on three sensors, and 3 other to monitor single phase. Is it possible to mix both?
Welcome, @Laurent, to the OEM forum.
Are you on a 3 wire supply or 4-wire? I guess that with 380 V, it’s 4-wire and 380 V line-line and 220 V line-neutral.
What “sensors” do you envisage? Do you mean current transformers to measure the current, or voltage sensors to measure voltage?
You’ve written so little that it is hard to know what you really want.
