Electric power transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines which facilitate this movement are known as a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is known as the "power grid" in North America, or just "the grid". In the United Kingdom, the network is known as the "National Grid".
A wide area synchronous grid, also known as an "interconnection" in North America, directly connects a large number of generators delivering AC power with the same relative frequency, to a large number of consumers. For example, there are four major interconnections in North America (the Western Interconnection, the Eastern Interconnection, the Quebec Interconnection and the Electric Reliability Council of Texas (ERCOT) grid), and one large grid for most of continental Europe.
The knowledge needed for laying electrical installations
Laying the electrical system not only at home, but each object is not the simplest of tasks. First of all, you must have the appropriate skills in the field of electrical engineering. You must also have knowledge typically technical, that is how laid the cables, where assembled the so-called cans, and how spread out the electrical system, if we consider the whole house. Specific challenges are posed by various types of sockets and switches located in such areas, like the kitchen or bathroom. That is where there is the greatest danger, and to correctly assemble the installation you have to have not only knowledge but also experience.
Employment in the construction electrician home
When it comes to houses, many electrical work is needed at the stage of construction. At the appropriate time work is carried out in respect of manual excavation in which the wires are subsequently stacked. Then, when the walls have been rebuilt there is a need to distribute the system throughout the house. He then are assembled separately, and all kinds of electrical outlets, of which the inhabitants of the house will later use. Of course, they are responsible for bringing the electrical system to the possibility of exploitation. Often electricians are also involved in installing electrical systems, such as intercom systems, which are quite useful, especially when dealing with a compact architecture.
