Earthing point is where conductor is directly connected to ground and its potential is always zero. Neutral is a return path in single phase system and in three phase system Neutral point will have zero potential if all the loads are balanced in the system. In un balanced three phase system even neutral point will have some potential

What is neutral earthing?
Neutral earthing are grounding options available for both low and medium voltage power systems. It provides point of zero volts.
How many earthing are required to install transformer?
Four number earthing are essential for installation of transformer as under : 1) Two earthing for transformer body. 2) Two earthing for Neutral Point. Note : Numbers of earthing may be increase as per the client requirement.
What is a difference between neutral earthing and body earthing?
here is no major difference between earthing and Grounding, both means "Connecting an electrical circuit or device to the Earth". This serves various purposes like to drain away unwanted currents, to provide a reference voltage for circuits needing one, to lead lightning away from delicate equipment. Even though there is a micro difference between grounding & earthing.Earthing and Grounding both is refer to zero potential but the system connected to zero potential is differ than Equipment connected to zero potential .If a neutral point of a generator or transformer is connected to zero potential then it is known as grounding. At the same time if the body of the transformer or generator is connected to zero potential then it is known as earthing.
How do I test my house's earthing?
Take 240V Lamp first check the voltage at Phase w.r.t neutral if lamp glows it means present voltage is OK now check the voltage w.r.t earth i.e. between phase & Earth point then lamp will glow. Now check between Neutral & Earthing Lamp should not glow. If these conditions are fulfill then your Earthing is OK.

What is the reason of the existence of a potential difference between the neutral point of the generator and the neutral point of the receiver?
Ground loop current, which is undesirable and every effort should be made to eliminate it.

There is no any such difference between Aniline point and mixed Aniline point . . . . .
How does an earthing transformer provide a neutral point for delta connected secondary?
There is normally no neutral point for a delta connection, Star or Y connections have grounded neutral points. So earthing transformers (or grounding transformers, GT, as they're called in this part of the world), are used to provide a neutral point in an otherwise ungrounded system. Typically they are found in utility transmission systems, where the grounding transformer provides a path for ground-fault current detection on the phases. The GT is connected in a zig-zag type arrangement such that positive-sequence (phase to phase) current is minimized, while zero-sequence (unbalanced) current presents a low-impedance path to ground. Usually, a reactor or resistor is inserted between the GT neutral connection and ground to limit the fault current to a level which will cause the detection to work but not damage the transmission equipment. See the links below for a simplified connection diagram and a somewhat more complex explanation.
What is the difference between an initial point of a vector and a terminal point?
The difference is the length of the vector.
Where is a voltmeter connected in a circuit?
Volt Meter is used to find the potential difference which is between the +ve or negative or between a Phase and Neutral etc. As it measure the potential difference, we need to connect in parallel which are tje extreme point of circuit starts and close, I mean completes.
