Complete Step By Step Answer:
Earthing is described as "the method of transmitting charges directly to the earth via low resistance wire to cause an instantaneous discharge of electrical energy." To have the least resistance path for fault current leakage, low resistance earthing wire is used.
Earthing may be achieved by attaching electrical appliances to earthing devices or electrodes located near or below ground level to ensure protection.
Under the ground surface, an electrode or earthing pad with a flat iron riser is mounted. It aids in the connection of the equipment's non-current-carrying metallic components.
The fault current from the equipment travels into the earthing system when an excess current is passing through the equipment or when a fault occurs in the system due to the current. The earth mat conductors assist in raising the voltage value proportional to the earth mat resistance compounded by a ground fault, as well as protecting the machinery from overload or fault current.
Grounding is the act of eliminating an object's excess charge by transferring electrons between it and another object of sufficient duration. The excess charge on a charged object is compensated when it is grounded by the passage of electrons between the charged object and a ground.

Note :
Earthing is accomplished by connecting the unit to the ground with an earth cable. If an earth wire is provided, it means that the current flowing through it to the ground has a very low resistance direction, preventing the individual from receiving a shock.
Grounding serves two purposes: it provides a direction for harmonics in the event of an unbalanced load, and it reduces the impact of high power surges. Grounding is done to secure power system devices as well as to provide a reliable return route from the unit to the power source.
