The grounding process is considered one of the most important steps that must be accomplished when installing an electrical network, whether in household electrical installations or in industrial facilities.  And what are the types of grounding process?  The most important uses of the grounding process?  Tools needed to complete the grounding process?  All these questions we will try to answer in this small educational article. Follow the explanation with me.


Definition of earthing :

 The grounding process is the connection of an electric wire between electrical appliances and the ground away from the source of electrical energy through what is called the electrode, which is a rod with a length of one meter or more, depending on the type of place for which the grounding process is to be established. It is made of brass, as the ground voltage is equal to  Zero, which allows excess electric current to flow to it without exposing people to electric shock, whether direct or indirect. This is why it is considered one of the most important techniques to maintain the safety of people and property connected to electricity. This is simply the mechanism of the grounding process.


Components of the grounding process:

 For the grounding process to work, some electrical components must be available for the success of the grounding process and for it to work effectively and with high efficiency. These are the most important equipment that must be available:


 Grounding electrode:

 It is a metal rod, often made of copper or aluminum, and it serves as a link between the ground and the electricity distribution box. It is buried in the ground, either fully or partially, as in the following picture:

 plate electrode:

 It is a plate made of galvanized iron, with a thickness of 6 centimeters or more, depending on the type of grounding. It is also buried in the ground with the iron rod, in order to reduce the resistance value of the ground. This picture shows the shape of the grounding plate.

Connecting equipment :

It is an accessories and tools to connect the various earthing elements well and effectively, And it has a role in securing a path with the lowest possible resistance, and these are pictures of some connecting tools, in the grounding process.

Types of grounding :

There are many different types of grounding that differ according to the type of electrical network that we want to work for the grounding process. 

GRID GROUNDING .
STAATIC GROUNDING.
GRID GROUNDING.
LOCAL GROUNDING .
TEMPORARY Grounding .


Grounding Uses :

The most important role for the grounding is to protect household appliances and electrical property, as well as protect people from electric shock :

Industrial facilities, 
household electrical installations, 
factories and laboratories, 
electrical power plants.


Conclusion:

 Before starting the grounding process, a suitable place must be chosen so that it is far from the source of electrical energy. You can put it in the comments section or on our Facebook page "Electrical Engineering Tips " .
