Pandon Dene Power Station
Pandon Dene Power Station was an early coal-fired power station situated on the Pandon Dene, to the east of Newcastle upon Tyne. History At the outset of their operations in 1889, the Newcastle-upon-Tyne Electric Supply Company (NESCo) were confined to operating within the eastern half of Newcastle. Their initial objective was to supply electricity for "4,500 ten candle-power lamps, of which 3,000 could be alight at one time." NESCo's first major step toward achieving this goal was the erection of their first power station, at Pandon Dene in the city's east end. The station was opened in 1890. Charles Merz worked at the station in 1892, prior to becoming a founder of his own electrical engineering consultancy Merz & McLellan. Design and specification Upon opening, the station generated electricity using two 75 kilowatts (kW) Mordey alternators, each driven by a conventional Robey steam engine, meaning the alternators operated at a slow speed. This gave the station an initial gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyne And Wear
Tyne and Wear () is a metropolitan county in North East England, situated around the mouths of the rivers Tyne and Wear. It was created in 1974, by the Local Government Act 1972, along with five metropolitan boroughs of Gateshead, Newcastle upon Tyne, Sunderland, North Tyneside and South Tyneside. It is bordered by Northumberland to the north and Durham to the south; the county boundary was formerly split between these counties with the border as the River Tyne. The former county council was based at Sandyford House. There is no longer county level local governance following the county council disbanding in 1986, by the Local Government Act 1985, with the metropolitan boroughs functioning separately. The county still exists as a metropolitan county and ceremonial purposes, as a geographic frame of reference. There are two combined authorities covering parts of the county area, North of Tyne and North East. History In the late 600s and into the 700s Saint Bede lived ...

Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

Riverside Branch
The Riverside Branch was a double-track branch line, which ran between Riverside Junction in Heaton and Percy Main West Junction in Percy Main. The line opened in May 1879, later being electrified in 1904, as part of the Tyneside Electrics network. It closed to passengers in stages between April 1954 and July 1973, with freight services continuing in to the late 1980s. It now forms part of Cycle Route 72 (Hadrian's Cycleway) on the National Cycle Network. History The Newcastle and North Shields Railway received Royal Assent on 21 June 1836, with the line opening between Carliol Square and North Shields on 18 June 1839. It ran along the north bank of the River Tyne, although due to the meandering course of the river, it ran some distance from the shoreline at the eastern end. The branch line, which was designed to more closely follow the shoreline of the Tyne, serving the rapidly developing industries and communities, was authorised in 1871. It was built along a route "th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Eastern Railway (UK)
The North Eastern Railway (NER) was an English railway company. It was incorporated in 1854 by the combination of several existing railway companies. Later, it was amalgamated with other railways to form the London and North Eastern Railway at the Grouping in 1923. Its main line survives to the present day as part of the East Coast Main Line between London and Edinburgh. Unlike many other pre-Grouping companies the NER had a relatively compact territory, in which it had a near monopoly. That district extended through Yorkshire, County Durham and Northumberland, with outposts in Westmorland and Cumberland. The only company penetrating its territory was the Hull & Barnsley, which it absorbed shortly before the main grouping. The NER's main line formed the middle link on the Anglo-Scottish "East Coast Main Line" between London and Edinburgh, joining the Great Northern Railway near Doncaster and the North British Railway at Berwick-upon-Tweed. Although primarily a Northern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotary Converter
A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting. They were commonly used to provide DC power for commercial, industrial and railway electrification from an AC power source. Principles of operation The rotary converter can be thought of as a motor-generator, where the two machines share a single rotating armature and set of field coils. The basic construction of the rotary converter consists of a DC generator (dynamo) with a set of slip rings tapped into its rotor windings at evenly spaced intervals. When a dynamo is spun the electric currents in its rotor windings alternate as it rotates in the magnetic field of the stationary field windings. This alternating current is rectified by means of a commutator, which all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Substation
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. They are a common component of the infrastructure, for instance there are 55,000 substations in the United States. Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control. The word ''substation'' comes from the days before the distribution system became a grid. As central generation stations became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wallsend
Wallsend is a town in North Tyneside, England, at the eastern end of Hadrian's Wall. It has a population of 43,842 and lies east of Newcastle upon Tyne. History Roman Wallsend In Roman times, this was the site of the fort of Segedunum. This fort protected the eastern end of Hadrian's Wall, which did not terminate at the western wall of the fort, but continued from its south-eastern corner down to the shore of the River Tyne. As David Breeze writes, "In the early nineteenth century, as recorded by Bruce, John Buddle the Younger had often seen the Wall foundations extending far into the river when swimming there as a boy." Pre-Conquest The withdrawal of the Romans from the Wall immediately brought the Picts from the north and shortly afterwards the Angles, sailing from near the mouth of the River Elbe with frequent raids both from sea and from land. Ida the Saxon laid waste to the whole of the north in 547 and Wallsend doubtless suffered in the general devastation. It was not un ...

Neptune Bank Power Station
Neptune Bank Power Station was a coal-fired power station situated on the River Tyne at Wallsend near Newcastle upon Tyne. Commissioned in 1901 by the Newcastle upon Tyne Electric Supply Company, the station was the first in the world to provide electricity for purposes other than domestic and street lighting. It was also the first in the world to generate electricity using three-phase electrical power distribution at a voltage of 5,500 volts. The station had an initial generating capacity of 2,800 kW, which was increased to 3,000 kW a year after the station opened, with the introduction of two 1,500 kW Parsons turbo alternators, the largest ever built at that time. The station closed in 1915, following the completion of an extension to Carville Power Station and the opening of Dunston Power Station. History At the beginning of the twentieth century, the use of electricity for general purposes began to be considered, and the Newcastle upon Tyne Electric Suppl ...

Transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits. Since the invention of the first constant-potential transfo ...

Reciprocating Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intr ...

Newcastle-upon-Tyne Electric Supply Company
The North Eastern Electric Supply Company (commonly abbreviated to NESCo) was responsible for the supply of electricity to a large amount of North East England, prior to the nationalisation of the British electricity industry with the Electricity Act 1947. The company was established as the Newcastle upon Tyne Electric Supply Company (also abbreviated to NESCo) in 1889, but was renamed the North Eastern Electricity Supply company as it expanded to supply the North East region. History The Newcastle upon Tyne Electric Supply Company was founded in Newcastle upon Tyne, North East England, in 1889 by the industrialist John Theodore Merz. The company was one of two that were founded in the Newcastle area that year, with the Newcastle and District Electric Lighting Company (DisCo) founded by Charles Algernon Parsons. A line was roughly drawn down the city's Grainger Street, with NESCo supplying the area to the east and DisCo that to the west. NESCo opened its first power station, Pan ...
