Answer Posted / surendar
Restricted earth fault function only protect the specified
zone .But sensitive earth fault function can protect all
earth faults(only applicaple for after start of ct point).
both protection analog inputs taking from neutral ct of
power transformer.but in ref taking ct reference for all
phases of ct for making protection of specified area .
setting of ref lesser then sef.sef also back up for ref.
both protection only applicable for star side for
transformer

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.
