General elements of electrical installations
The main of electrical installations is to meet all the goals that were required during the phase of the project is:
That will provide a better servicethan you will meet the requirements of the different elements that transform as receivers as needed.
And within the concept of electrical installations can take all kinds of facilities from thegeneration and use of electricity likewise passing through the stages of processing and distribution.
Electrical installations are classified as:
1. This is high retention (85, 115, 230, and 400 KV)
2.Extra high retention this can be more than (400 KV)
3. Median retention (69 KV)
4. Distribution and low retention (23, 20, 13.8, 4.16, 0.440, 0.127 KV)
This classification according to theintentions as they are employed on electrical systems.
What do you mean electrical installations?
That this is called the set of elements required and able to drive and transform electrical energy.
Inorder to be used in machines and receivers so that the end use.
But also to have these following requirements

• It will be safe from accidents and fires
• Efficient and economic
• Accessible andeasy maintenance
• Meet the technical requirements set by the building regulations and electrical industries.

Types of electrical installations according to their types:

* High voltageinstallation:
Are those facilities where a maximum potential difference between two lines is greater than 1,000 volts (1 kV).

* Low voltage installations:
they are the more general case ofelectrical installations in these cases the maximum potential difference between two conductors is less than 1,000 volts (1kV) but greater than 24 volts.

* Installation of low voltage:
these arefacilities where maximum potential difference between two conductors is less than 24 volts.

* Generating facilities:
Are the electromotive force generated electricity and therefore from other forms...
