Answer Posted / meenakshi
By Earthed system, we mean a three phase system whose star
point is grounded directly. In this case, in the event of
the earth fault, the voltage in the faulty phase will
become zero. The voltage between the healthy phases and the
ground will be the same, 11kV/1.732 or 6.6/1.732.
However, in case of an earth fault in an ungrounded system,
the voltage between the healthy phases and the ground will
be equal to the phase to phase voltage. i.e. 11kV or 6.6 kV.
