How to converge 3 phases of simulink voltage onto a simscape VI measurement which accepts 1 port

As mentioned, I'm wanting working between simulink and simscape libraries. My voltage source block outputs 3 phases of voltage, although the measurement block that I need accepts a single connection with 3 signals. Notsure how to get around this as cant use a mux. Any help would be much appreciated!

This block lets you switch between one line representations of 3 phase wires: https://www.mathworks.com/help/sps/ref/phasesplitter.html;jsessionid=12d81ff0f3faaf382533c296ec45

All you have to do is right click on the current & voltage sensor, choose Simscape > Modeling option > expanded three-phase ports, as you can see in the attached screenshot ![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1289120/image.png)

You can directly use a Controlled Voltage Source (Three-Phase) in Simscape Electrical. Assuming that the Subsystem you have is using blocks from the Simscape technology you can directly connect it to the measurement sensor by changing the 'Modeling option' dropdown in the Current and Voltage Sensor (Three-Phase) to 'Expanded three-phase ports'. I hope this helps.
