Hi, can anyone help me see why there is no phase voltage below 0V?

 

I am not able to spot a -ve Voltage Source anywhere.......

 

Why would you expect to see voltages below 0V?

Thank you for replying, i added load and measure Vphase to neutral, i can see the right waveform

Certainly the no-load voltage of most power circuits is rather different from the full load voltage. That is to be expected. AND I am relieved that the TS discovered the solution.
