What is min and max voltage between earth and neutral/phase
if it perfect earthing?
Answer Posted / priyank
earth to phase : 230V
phase to neutral : 230V
earth to neutral : 0V(when balanced load)
earth to neutral : >0V when unbalanced load

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
