Hi:
What voltage could I expect to see on the output terminals of a VSD say at 10 HZ Three phase System

Hello LesL
At 10 Hz, you would get a voltage of 20% of the line voltage (assuming 50Hz supply) or 16.6% of line voltage for a 60Hz system.
You will probably have dificulty measuring this due to the PWM nature of the output waveform.
Best regards,
Mark.

Moreover, it depends upon the V/HZ ratio setting in inverter.
