Answer / raghavendran

I am not sure, but this is what I can understand from the
condition given below:

For case 1:The neutral - earth path which should be at 0
potential under normal operating condition is at 10 Volts.I
think the system is facing unbalanced condition i.e a
condition called as 'Neutral Shifting'.So the unbalanced
current will flow from Neutral to earth.the earthing has to
be proper so that personal and the equipment will be safe.

For case 2:The earth is at a higher potential when compared
to the neutral.hence it may cause 'reverse feeding' or 'back
feeding' of the current from earth towards the neutral.An
equally dangerous condition.

Answer / parth belani

As Raghvendran said, the system is having 'neutral
shifting' condition.
In other words, In case 1, The system is FLOATING at +10
volts. In case 2, the system is floating at -10 volts.
