What is difference between earthing & Grounding?

Grounding it Balance point for three phase system ( star type ) to let KERCHOF low it right Ir+Iy+Ib=0

if total current it not Equal zero the value go to grounding point.

Earthing it a system to minimize risk of receiving an electric shock( short circuit , over current & load balnce  

Ex.if touching metal parts when a fault is present it will safe human fro S.C shuck 

NOTHING

The same meaning diffrent terminology

One used by the Americans the othe used by the English

Earthing and Grounding are actually different terms for expressing the same concept

both have same meaning i.e. producing low reluctance path to the conductor during high voltage, term earthing is used basically in developed countries like europe, britain,u.s and term earting is used in countries like india,  

Earthing means connecting the dead part (it means the part which does not carries current under normal condition) to the earth. For example electrical equipment’s frames, enclosures, supports etc.While grounding means connecting the live part (it means the part which carries current under normal condition) to the earth. For example neutral of power transformer.

The purpose of earthing is to minimize risk of receiving an electric shock if touching metal parts when a fault is present. While the purpose of grounding is the protections of power system equipment and to provide an effective return path from the machine to the power source. For example grounding of neutral point of a star connected transformer.

Ground is a source for unwanted currents and also as a return path for main current some times. While earthing is done not for return path but only for protection of delicate equipments.

earthing connection done with the body of electrical equipment  such as zero potential . grounding connection always done with the neutral of transformer .
