Answer Posted / meenakshi
Stray or ghost voltages occur from capacitive coupling,
which takes place between energized circuits and non-
energized non-connected adjacent wiring.
practical occurance : When facilities or buildings are
built and wired, it's very common for the electricians to
pull extra wire thru the conduit for future use. These
wires are typically left unconnected until needed.at this
situation coupling effect takes place as explained above.

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.
