Isolation Transformer is used to block the DC components.
It has 1:1 ratio.There are many causes to produce/introduce
the DC components. If we do not block these components then
if may effect on the output. Isolation Transformer can be
used within in a single circuit. So, it is not correct that
the isolation transformer is always used to isolate the two
circuits.

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.
