History of electric power industry
Although electricity had been known to be produced as a result of the chemical reactions that take place in an electrolytic cell since Alessandro Volta developed the voltaic pile in 1800, its production by this means was, and still is, expensive. In 1831, Michael Faraday devised a machine that generated electricity from rotary motion, but it took almost 50 years for the technology to reach a commercially viable stage. In 1878, in the US, Thomas Edison developed and sold a commercially viable replacement for gas lighting and heating using locally generated and distributed direct current electricity.
The world's first public electricity supply was provided in late 1881, when the streets of the Surrey town of Godalming in the UK were lit with electric light. This system was powered from a water wheel on the River Wey, which drove a Siemens alternator that supplied a number of arc lamps within the town. This supply scheme also provided electricity to a number of shops and premises to light 34 incandescent Swan light bulbs.
Additionally, Robert Hammond, in December 1881, demonstrated the new electric light in the Sussex town of Brighton in the UK for a trial period. The ensuing success of this installation enabled Hammond to put this venture on both a commercial and legal footing, as a number of shop owners wanted to use the new electric light. Thus the Hammond Electricity Supply Co. was launched. Whilst the Godalming and Holborn Viaduct Schemes closed after a few years the Brighton Scheme continued on, and supply was in 1887 made available for 24 hours per day.
In early 1882, Edison opened the world?s first steam-powered electricity generating station at Holborn Viaduct in London, where he had entered into an agreement with the City Corporation for a period of three months to provide street lighting. In time he had supplied a number of local consumers with electric light. The method of supply was direct current (DC).
More and more jobs for electricians in garages
Electrical services are increasingly concerned electricity car. As it turns out, more and more modern cars are even drugged technical solutions in the field of electrical and electronics and even a minor fault causes that need to enlist the help of a specialist in this field. Different types of probes and controls in cars are very important indicators that allow the user to monitor the level of a suitable fluid and the overall control of the car. In case of failure may occur up to a serious fault, because electrical services increasingly possible to repair in this area.
Education in the technical profile electric
Technical profile electrician certainly is much less likely to be selected than other specialties, such as construction. This is because the vocational subjects, where young people learn from this direction are much more difficult, since they concern the often incomprehensible for youth affairs physical and mechanical properties. However, anyone interested in this field and who want to learn a profession electrician certainly can handle, if studied systematically. Completion of such a school is crowned with theoretical and practical exam, which entitles you to perform electrical services, such as installation and repair of the system.
