Grounding Definition

The grounding is a safety mechanism that is part of the electrical installations and consists of driving eventual deviations of the current to the earth , preventing the user from coming into contact with the electricity.

This means that a certain sector of the facilities are linked, through a conductor, to the ground so that, in the event of an unexpected derivation of the current or a failure of the insulation, people do not get electrocuted when they come into contact with the devices connected to that installation.

Ground wire, well to ground or ground connection are other names given to this union, which began to be used as early as the 19th century.Specifically, it began to be used when the use of telegraph systems.

When starting up a grounding installation, it must be taken into account that two fundamental elements such as land, which is the land where It will proceed to dissipate the relevant energies or electricity, and the grounding.This connection or installation, meanwhile, is composed of electrodes or javelins, the grounding terminals, the ground link line and , finally, protection drivers.

Also called ground pole or ground , grounding involves the use of a piece of metal that is buried in the ground and can even be connected to the metal sectors of a structure .Through a insulating cable , this piece of metal is connected to the electrical installation and, through the plug bases, to the devices connected to electricity.The grounding also includes the use of a differential switch that is responsible for opening the electrical connection when registering a current flow to the ground.

The earth is, in short, a surface that can dissipate the electrical current it receives.What we call grounding consists of a mechanism that has the pieces buried metal (called javelins , spades or electrodes ) and conductors of different classes that link the various sectors of the installation.

The lightning rods , for example, work with a grounding system, driving the discharge to a low resistance ground.

In addition to all the above, we cannot ignore the fact that there are three different types of earthing or earthing: 1-DC system.It is the one that occurs in numerous technological devices that are currently part of our life, such as computer cards, and is identified because it occurs as a difference from the voltages of the existing circuits.2-AC system to ground of alternating current.It is the one that is known in a more generalized way and the one that takes place due to the difference in voltages in buildings and constructions of different types.3-Electrostatic ground system.The interrelation between the loading of a container and its fluid is what propitiates this.
