siemens full form, In physics, a siemens is a unit of electrical conductance, which is the reciprocal of an ohm. In the metric system, the mathematical prefix “milli” or “micro” may be appended to “siemens” as appropriate.
In English literature and speaking, an ohm was originally defined as a one-volt potential difference between two points of conducting material – although it has since been redefined in terms of resistance instead – and this historically led to confusion with respect to what a siemens might represent. Siemens specializes primarily in manufacturing electrical equipment such as generators and coils primarily for 35 different markets especially those related to power generation natural gas transmission oil/gas exploration fields.
It has developed a unique position in the industries of gas turbines and generators, high voltage equipment, transformers, power automation equipment, wind turbines, compressors turboexpanders.
Siemens AG is one of the oldest electrical engineering companies in the world. The company was founded by Werner von Siemens and his brother Karl Wilhelm Siemens in Berlin in 1847. The company opened its first workshop on 12 October 1847 and a second one in January 1848. Siemens & Halske was entered into the commercial register of the General-State Courts (later Supreme Court) at Berlin on 14 April, registered as “Company on 29 May, and received a royal license to conclude foreign contracts on 24 June.”
The first international agreement was contracted by Siemens & Halske with J.P. Morgan & Co., an American mercantile bank in London 30 August 1895 for lighting cities of New York City, London and Paris with incandescent lamps made by the German firm. A year later 28 September 1896 Queen Victoria of England inaugurated the London Electric Supply Corporation ELiC with an extremely long speech in which she gave Siemens & Halske “the honor of the electric lighting” to England.
Siemens & Halske grew rapidly in the late 19th century, building their first large plant for incandescent lamps at Lichterfelde near Berlin. During this period they installed one of the first electrical systems in Russia (1881). They also supplied equipment to Germany’s colonies and foreign markets, including Cuba, Japan and Siam. The company was involved throughout much of the Balkans region as part of a joint venture with Austro-Daimler. This included installing electric streetcars in Sofia and Belgrade.
Siemens is a worldwide company that makes and sells power plants, lights for homes and offices as well as other equipment. It also provides energy services like gas supply through its subsidiary AGSO (Augsburg-Griesbach-Solarpark).
The history of Siemens spans back over 200 years to 1847 when Werner von Siemens built the first steam engine without any internal combustion components whatsoever. This was followed by Siemens’ development of the alternating current in 1885. This achievement is particularly impressive when one considers that the power grid wouldn’t be developed for another 60 years after that, meaning Siemens had to invent components used until this day just to get their product working.
The company has evolved over time into an international powerhouse with hundreds of subsidiaries and over 300,000 employees. In 2011 alone, Siemens had a revenue of €73 billion.
Since the wind turbine factory is located in Augsburg alongside its gas power plant it’s not surprising that they have to deal with a lot of waste heat from the turbines as well as CO2 emissions from the gas power plant. The power plant alone has a capacity of 829 megawatts, which is enough to provide energy for 1 million households. It’s located in a naturally occurring gas field and uses the “Stuttgart process” – an environmentally friendly method of recycling any emissions for use as fuel or process steam.
