what is the difference between the following 2 situations ? 1)Line & Neutral=240V Line & Ea..

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.

I do wonder why current is present in neutral wire?i check single phase lead current feeding air conditioner...on its phase its current was 10A while same was 10A in neutral...as we know in neutral voltage is zero so if voltage is zero then how current appears on amp meter? my second observation is (just imagination)when I touch phase wire it give me shock but when i touch neutral nothing happens although as above its carrying current(amps) third but with same logic...as in simple Alternate current sine curve there is + and there is negative peak.means every time phase changing so how come every time same phase and same neutral stand (pardon for english mistakes)
