What is the Grounding ?

Grounding is one of the very often hear terms related to electricity . Grounding , electrical installations , houses and all the plumbing parts that are not under tension , with a non- zero- conductors and related sections of soil mass of conductors placed in the appropriate sections of a conductive object (electrode ) is called to connect the grounding
What is the purpose of the grounding ?
Leakage currents through the ground on the device and the security of living will be provided so that static electricity will flow from the soil and to prevent damage to the devices .
Also occur in the event of an error that may occur in step and touch voltages extent to endanger human life or avoid completely eliminate hazardous voltages .
Grounding , such an error may occur if one of the actions to be applied in order to ensure people's lives .
What are the kinds of the earth ?
1 - Protection Ground
2 - Your Ground
3 - Function Ground
4 - Lightning Against the Ground
There are several types of cable homes electrical grid ?
1 - Neutral Cable
2 - Phase cable
3 - Ground cable
Buildings, land line that is?
Distribution networks supplying power transformers stars created by connecting the star points . This star is from the tip of the neutral , and the ground plate and grounded. Power cable enters the building, usually 4 units .
PHASE 3 out of these cables . So you are on the electricity . One of the nötr'dür . This is called three-phase system . This three- phase line, is distributed evenly into the building . So the entrance to the building from the main electrical box, each on a separate line in the three -phase distributed in a floor or floors . If the neutral line is one and the one that goes to all floors .
Electrician lining the outside of the building electrical system of the building is a large copper ground rod or copper plate in a specific flash / embeds . This building is a cable attached to the copper rod into the entrance of the first building phase and nötr'ün brings up the main electrical box . From this point on , the entire building , all apartments, a phase , a neutral and a ground line goes . Nötr'e two holes in the middle phase and is connected to a grounded electrical outlet , metal protrusions on the outer side is connected to the ground line .
The ways in which the grounding system made ​​of?
1 - Rod grounding electrode
2 - Crowbar grounding in the form of
3 - Plate grounding electrode
4 - Strip grounding electrode with
5 - Metal grounding electrodes
6 - The underground water pipes and ground installations
7 - Building Embracing grounding electrode
