I am trying to measure 3 phase 3wire and 3 phase 4 wire L_L voltage and L_N voltage.Circuit i am looking is common for both. In star connection i will get an neutral point for reference to read the accurate reading in delta connection i wont have neutral reference but i wanted to create virtual neutral point. can someone suggest me circuit that can interface to MCU with above requirement
- How to create virtual neutral point for delta connection
- how can i differentiate real and virtual neutral point
- is it safe when actual neutral point connected to virtual neutral point.
- i have seen some application using this kind of circuit,I could not able get operation / functionality.mainly used for star and delta connection.
- Is there any other technique where i could use Y and delta connection as common 78m6631 MCP3914 ADE7880
but i have used this IC there is no issue while reading star connection. but when connected in delta it make huge difference.
