Necessary to lay the installation, information concerning the electricity

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.


Some historical facts

By 1890 the electric power industry was flourishing, and power companies had built thousands of power systems (both direct and alternating current) in the United States and Europe. These networks were effectively dedicated to providing electric lighting. During this time a fierce rivalry known as the "War of Currents" emerged between Thomas Edison and George Westinghouse over which form of transmission (direct or alternating current) was superior.8 In 1891, Westinghouse installed the first major power system that was designed to drive a 100 horsepower (75 kW) synchronous electric motor, not just provide electric lighting, at Telluride, Colorado.9 On the other side of the Atlantic, Mikhail Dolivo-Dobrovolsky built a 20 kV 176 km three-phase transmission line from Lauffen am Neckar to Frankfurt am Main for the Electrical Engineering Exhibition in Frankfurt.10 In 1895, after a protracted decision-making process, the Adams No. 1 generating station at Niagara Falls began transferring three-phase alternating current power to Buffalo at 11 kV. Following completion of the Niagara Falls project, new power systems increasingly chose alternating current as opposed to direct current for electrical transmission.11

Developments in power systems continued beyond the nineteenth century. In 1936 the first experimental HVDC (high voltage direct current) line using mercury arc valves was built between Schenectady and Mechanicville, New York. HVDC had previously been achieved by series-connected direct current generators and motors (the Thury system) although this suffered from serious reliability issues.12 In 1957 Siemens demonstrated the first solid-state rectifier, but it was not until the early 1970s that solid-state devices became the standard in HVDC.13 In recent times, many important developments have come from extending innovations in the ICT field to the power engineering field. For example, the development of computers meant load flow studies could be run more efficiently allowing for much better planning of power systems. Advances in information technology and telecommunication also allowed for remote control of a power system's switchgear and generators.

Work on the home electricity

Although many people isolated attempts to control the domestic installations, usually professional help is highly desirable especially in more complex cases. As far as changing a light bulb or perform other similar tasks require more visits electrician so much already in the case of laying wires or installation of distribution are more complicated. Isolated executed electrical installations can make later, at the stage of operational problems arise, for example, through the inclusion of too many devices to the power supply circuit may occur. So let's take care of it, to the more complex work carried out specialist, because working with electricity can be dangerous for inexperienced employee.
