- Instantaneous — The output voltages, [va vb vc], are equal to the values of the input port S.
The signal input and output should be same..
Could anyone help me this question? Many thanks.

Hi Yunzhong,
I understand that you are facing an issue with the difference in the value measured by the sensor and the original value. The reason of the discrepancy is that 'Current and Voltage Sensor" block measures phase to phase voltage by default. The phase to phase voltage is square root 3 times the phase to ground voltage.
You can change the 'Voltage measurement type' from phase-to-phase to phase-to-ground voltage. You may refer the following documentation to learn more about the "Current and Voltage Sensor" block:
Hope this helps.

So, it was the setting issue with Current and Voltage Sensor block which makes sense now because that will cause the amplitude to become root three times the original value, and the phase change when using controlled voltage source but glad to know that this issue is resolved.
