What is the basic difference between earthing, ground and
neutral?
Answers were Sorted based on User's Feedback
Answer / rabi
Neutral- it is a point where the sum of the current meeting
at that point is zero. E.g. in three phase star connected
winding the neutral is the point where all winding is
meeting at a same point obviously at normal operating
condition.
Ground- ground and earth both are same term. it may be a
reference point for in an electrical circuit from which
other voltages are measured, or a common return path for
electric current, or a direct physical connection to the
Earth.
Earthing -it is nothing but the process of connecting all
the neutral points of the equipment and non-conductive
exposed part of the metal structure to earth.

Answer / kalidassallinterview
Earthing : To connect the machinery body to ground by a
conductor it is called earthing.
Ground : Ground is a one terminal, it having zero volts.
Neutral: The junction of 3phase. In balanced condition this
voltage is zero.

Answer / jaymin shah
Earthing: to protect from shock we have toe earth all the equipement and ins. Include AC,socket
Ground: to protect equipement body we have to ground it..
Neutral: it is completing the ckt.

Answer / harshad pingle
Neutral= 0=In=Ir+Iy+Ib i.e summation of three currents
equals to the neutral current which is zero.
Grounding= Zero potential point. It may be the floating
neutral of star connected system.
Earthing= The system connected to earth where the system
max leakage current can flow.

Answer / sendhur
Ground and earth are one in the same, and don't normally
carry any current - they are "reference" ground.
Neutral is the grounded side of an AC outlet. It carrys
current, it is the return path for AC. Although it is
grounded at the utility pole, it should not be grounded
anywhere e

EARTHING: it is defined as connecting the metal body or non current carrying part of electrical installation to solid mass of earth

Answer / rehan khan
in Earthing system we connect the system with the earth pysically for the sake of safety . while ground is not physically connected to earth but is a reference potential point and return flow path for currrent from different parts of circuit.........

Answer / pankaj agarwal
earthing means neutral earthing. it is connecting the
current carrying points in the circuit to earth. this is
done for the purpose of operation of earth fault relays.
grounding means equipment earthing. it is connecting tha
non current carrying parts, like metallic enclosure, to the
earth. this is done for personnel safety.
neutral is a common return path in a multi phase circuit,
generally earthed to provide a reference voltage.

As we know multiplicity factor derivation equation is as below MF = main c t ratio / main p t ratio * meter c t ratio / meter p t ratio * meter dial constant Where in digital meters for HT kwh import export now a days meter constant are calibrated already which is 1 So my question is For HT 11kv 110 v line values are as below Main c t and p t ratio are 11000 v and 110 v and 20/5 means 20 amp and 5 amp Now meter values are 11000/√3/110√3 and primary and secondary amp are displayed as -/5 amp on kwh meter so what will be the MF for this meter ?
