High Voltage
High voltage electricity refers to electrical potential large enough to cause injury or damage. In certain industries, ''high voltage'' refers to voltage above a certain threshold. Equipment and conductors that carry high voltage warrant special safety requirements and procedures. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to produce electrical arcs, for ignition, in photomultiplier tubes, and in high-power amplifier vacuum tubes, as well as other industrial, military and scientific applications. Definition The numerical definition of depends on context. Two factors considered in classifying a voltage as high voltage are the possibility of causing a spark in air, and the danger of electric shock by contact or proximity. The International Electrotechnical Commission and its national counterparts (IET, IEEE, VDE, etc.) define ''high voltage'' as above 1000 V for alternating current, and at ...

HVDC Kingsnorth
HVDC Kingsnorth was a high-voltage direct-current (HVDC) transmission system connecting Kingsnorth in Kent to two sites in London. It was at one time the only application of the technology of high voltage direct current transmission for the supply of transformer stations in a city, and the first HVDC link to be embedded within an AC system, rather than interconnecting two asynchronous systems. It was also the first HVDC scheme to be equipped with self-tuning harmonic filters and to be controlled with a "Phase Locked Oscillator", a principle which subsequently became standard on all HVDC systems. It was designed in the late 1960s and went into service in 1974. It ran from Kingsnorth power station as a 59 kilometers long bipolar (3-wire) underground cable. The positive pole operating at a voltage of +266 kV terminated at the converter station in Beddington near Croydon. The negative pole continued to run a further 26 kilometers at -266 kV line to a similar station at Willesden in N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornsea Wind Farm
Hornsea Wind Farm is a Round 3 wind farm which began construction in 2018. Sited in the North Sea off the east coast of England, the eventual wind farm group is planned to have a total capacity of up to 6 gigawatt (GW). The development has been split into a number of subzones. The 1.2 GW Project 1 gained planning consent in 2014. Construction of Hornsea One started in January 2018, and the first turbines began supplying power to the UK national electricity grid in February 2019. The turbines were all installed by October 2019 and the equipment fully commissioned in December 2019. With a capacity of 1,218 MW, it was the largest in the world on its completion. A second 1.4 GW Project 2 was given planning consent in 2016. First power was achieved in December 2021, and it became fully operational in August 2022 overtaking Hornsea One as the largest offshore wind farm in the world. In 2016 a third subzone was split into two projects Hornsea 3 and 4, with appr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gwynt Y Môr
Gwynt y Môr (Welsh: meaning ''sea wind'') is a 576-megawatt (MW) offshore wind farm located off the coast of Wales and is the fifth largest operating offshore windfarm in the world. The farm has 160 wind turbines of tip height above mean sea level. Planning consent for the project was granted on 3 December 2008. The project has a value of 2 billion Euros, of which 1.2 billion Euros were spent on turbines and electrical connections.

Greater Gabbard Wind Farm
Greater Gabbard is a 504 MW wind farm, built on sandbanks off the coast of Suffolk in England at a cost of £1.5 billion. It was completed on 7 September 2012 with all of the Siemens SWT3.6–107 turbines connected. Developed as a joint venture between Airtricity and Fluor, it is now jointly owned by SSE Renewables and Innogy. A 336 MW extension of the wind farm called Galloper was commissioned in April 2018. History Development rights were secured from the Crown Estate in 2003. The project was originally developed by Greater Gabbard Offshore Winds Limited (GGOWL) which was a joint venture between Airtricity and Fluor. Airtricity was subsequently bought by Scottish & Southern Energy who then bought out Fluor's 50% stake. Fluor were contracted to design, supply, install and commission the balance of the plant. Scottish & Southern sold a 50% stake to RWE, the owners of Npower, in November 2008 for £308m. The project was given the go-ahead in May 2008 and work ...

Fawley Tunnel
Fawley Tunnel is a diameter, long tunnel under Southampton Water between Fawley Power Station and Chilling near Warsash. It was constructed between 1962 and 1965 to carry two 400 kV circuits as part of the National Grid. The tunnel was built with a 3 feet 1.125 inch gauge railway to help with maintenance access. The railway was operated with a single battery powered locomotive that was scrapped in the late 70s.

East Anglia Array
The East Anglia Array is a proposed series of offshore wind farms located around 30 miles off the east coast of East Anglia, in the North Sea, England. It has begun with the currently operational East Anglia ONE, that has been developed in partnership by ScottishPower Renewables and Vattenfall. Up to six individual projects could be set up in the area with a maximum capacity of up to 7.2 GW.

Area Of Outstanding Natural Beauty
An Area of Outstanding Natural Beauty (AONB; , AHNE) is an area of countryside in England, Wales, and Northern Ireland, that has been designated for conservation due to its significant landscape value. Areas are designated in recognition of their national importance by the relevant public body: Natural England, Natural Resources Wales, and the Northern Ireland Environment Agency respectively. In place of AONB, Scotland uses the similar national scenic area (NSA) designation. Areas of Outstanding Natural Beauty enjoy levels of protection from development similar to those of UK national parks, but unlike national parks the responsible bodies do not have their own planning powers. They also differ from national parks in their more limited opportunities for extensive outdoor recreation. History The idea for what would eventually become the AONB designation was first put forward by John Dower in his 1945 ''Report to the Government on National Parks in England and Wales''. Dower ...
