For safety reasons electrical systems are normally grounded (for example, an a.c. supply system's neutral is grounded at the transformer). By common consent, the ground (or earth) is then taken as being the zero potential point of reference, from which potentials in a grounded electrical system can be measured.

An electrical ground is a path created so that stray electricity can be diverted to the Earth, rather than through (potentially) a person, if a short should occur.
A grounded outlet or other device is connected via a green-insulated, or bare wire to the ground buss bar in a fuse box or breaker panel. This bus bar is connected by a wire to either a cold water pipe (as close to the point it enters a building as possible), or to an 8-foot ground rod (which is driven into the ground outside of a building), or both.
Answer for countries in Europe and other world areas running a 50 Hz supply service.
Never ever use a cold water pipe or any other pipe that happens to be going into the ground because there is no guarantee that it is securely bedded-into the soil to be an effective and safe earthing point.
Instead, always use the earthing point provided by your electricity service supplier where the incoming electrical mains cable enters your property. (In some countries this is called the "service entrance".)
In certain spacial circumstances a proper earthing plate, that has been designed and made specifically for that purpose - and which has been correctly installed into the ground by a licensed electrician - may have to be used.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

A safety procedure where electricity is channeled directly into the ground?
grounding
Is it true that a building can be protected from lightning by grounding?
Lightning can still strike a building, but grounding makes the electricity in the lightning flow into the ground, making it a less of a danger to the people in the building. Yes its true
What is the conductive connection between an electrical circuit equipment in the Earth?
The movement of water is like the flow of the electricity. Electricity must have a complete path for the flow. This movement is called?
Can you use a light bulb without grounding?
what is the relationship of light bulb and grounding
What if a 3 prong dryer chord is not grounded?
Actually nothing will happen , unless an short occurs in a electrical box, or, an appliance. Electricity aways returns to a neutral wire in the service panel. A grounding wire is a safety feature providing another source of return current when a short occurs They usually are connected to a grounding pole 8 feet into the earth.
How does good grounding in your house affect electricity bills?
'Good' grounding, or earthing, has no effect whatsoever on electricity bills. Electricity bills are based on your property's energy consumption. Grounding is simply a safety feature of the electrical system; it draws no energy.
A safety procedure where electricity is channeled directly into the ground?
grounding
What is the definition of grounding as in electricity?
It is where a point in a circuit is at zero voltage.
Why is grounding electricity so important?
Grounding is important, because it protects users of electricity from potentially fatal electrical shocks. This is accomplished through bolting, clamping or other effective mechanical means to provide an effective grounding path to the earth instead of through the user.
An invention to reduce the effects of static electricity?
A grounding wire or strap.
What are grounding mats used for?
Grounding mats are used when working on electronic components to drain off static electricity. Static electricity develops high voltages (the spark that jumps from your hand to a doorknob in winter is static electricity) and these voltages can damage sensitive electronics.
What are electrolyte plates in a grounding system?
Electrolyte plates in a grounding system are electrically grounded metal plates on which a person stands to discharge static electricity picked up by his body. This is called grounding.
What are some dangerous situations involving static electricity?
Grounding is the only way to handle static electricity. Ground all metallic parts to one another and then take the ground wire to installed grounding electrodes.

How do you overcome the dangers of static electricity?
The best way to overcome the dangers of static electricity is to use proper grounding so that the accumulated charges are discharged.

What does the third grounding wire of a three-pronged plug do?
It provides a safe path for errant electricity. Never cut it off.
