Mains Electricity
Mains electricity or utility power, power grid, domestic power, and wall power, or in some parts of Canada as hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electric grid in many parts of the world. People use this electricity to power everyday items—such as domestic appliances, televisions and lamps—by plugging them into a wall outlet. The voltage and frequency of electric power differs between regions. In much of the world, a voltage (nominally) of 230 volts and frequency of 50 Hz is used. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other combinations exist, for example, 230 V at 60 Hz. Travellers' portable appliances may be inoperative or damaged by foreign electrical supplies. Non-interchangeable plugs and sockets in different regions provide some protection from accidental use of appliances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mains Electricity By Country
Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some countries have more than one voltage available. For example, in North America the supply to most premises is 2 phase plus neutral, with 240 volts between the phases and 120 volts between either of the phases and neutral. Most sockets are attached to the latter 120 V and neutral. By connecting across the phases, 240 V is available for large appliances. Often different sockets are mandated for different voltage or current levels. Voltage, frequency, and plug type vary, but large regions may use common standards. Physical compatibility of receptacles may not ensure compatibility of voltage, frequency, or connection to earth (ground), ...

Electricity Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same rela ...

Public Utility
A public utility company (usually just utility) is an organization that maintains the infrastructure for a public service (often also providing a service using that infrastructure). Public utilities are subject to forms of public control and regulation ranging from local community-based groups to statewide government monopolies. Public utilities are meant to supply goods/services that are considered essential; water, gas, electricity, telephone, and other communication systems represent much of the public utility market. The transmission lines used in the transportation of electricity, or natural gas pipelines, have natural monopoly characteristics. If the infrastructure already exists in a given area, minimal benefit is gained through competing. In other words, these industries are characterized by ''economies of scale'' in production. There are many different types of public utilities. Some, especially large companies, offer multiple products, such as electricity and na ...

Main Course
A main course is the featured or primary dish in a meal consisting of several courses. It usually follows the entrée ("entry") course. Typically, the main course is the meal that is the heaviest, heartiest, and most intricate or substantial on the menu. Typically, meat or fish is the main component; but, in vegetarian meals, the main dish will occasionally make an effort to resemble a meat course. Usage In the United States and Canada (except Quebec Quebec ( ; )According to the Canadian government, ''Québec'' (with the acute accent) is the official name in Canadian French and ''Quebec'' (without the accent) is the province's official name in Canadian English is one of the thirte ...), the main course is traditionally called an "entrée". English-speaking Québécois follow the modern French use of the term entrée to refer to a dish served before the main course. According to linguist Dan Jurafsky, North American usage ("entrée") retains the original Frenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mains (Scotland)
A mains ( gd, mànas) in Scotland is a farm, or the buildings of a farm. This may include the farmhouse, farm buildings such as a byre, dairy, and workers' cottages. It is pseudo-plural, actually being a Lowland Scots corruption of ''domains'' or '' demesne'',The ''Shorter Oxford English Dictionary'' and so is never used in the form "main" (except occasionally in the tautological "main farm", although this usage is not traditional). Definition The mains was usually the principal farm on an estate, or at least the one with the most fertile ground. The rough equivalent in England would be a ' home farm' (or perhaps 'manor farm', but not a 'manor' or 'manor house'). The laird's house – if there was one – may have been nearby or some distance away, but is not usually considered part of the mains. Many mains remain as working farms, while others have been converted to residential accommodation. Sometimes the buildings and/or farm have disappeared altogether, and only the nam ...

BMX Racing
BMX racing is a type of off-road bicycle racing. The format of BMX was derived from motocross racing. BMX bicycle races are sprint races on purpose-built off-road single-lap race tracks. The track usually consists of a starting gate for up to eight racers, a groomed, serpentine, dirt race course made of various jumps and rollers and a finish line. The course is usually about wide and has large banked corners, which are angled inward, that help the riders maintain speed. The sport of BMX racing is facilitated by a number of regional and international sanctioning bodies. They provide rules for sanctioning the conduct of the flying, specify age group and skill-level classifications among the racers, and maintain some kind of points-accumulation system over the racing season. The sport is very family oriented and largely participant-driven, with riders ranging in age from 2 to 70, and over. Professional ranks exist for both men and women, where the age ranges from 17 to over 40 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Main
A water distribution system is a part of water supply network with components that carry potable water from a centralized treatment plant or wells to consumers to satisfy residential, commercial, industrial and fire fighting requirements. Definitions Water distribution network is the term for the portion of a water distribution system up to the service points of bulk water consumers or demand nodes where many consumers are lumped together. The World Health Organization (WHO) uses the term water transmission system for a network of pipes, generally in a tree-like structure, that is used to convey water from water treatment plants to service reservoirs, and uses the term water distribution system for a network of pipes that generally has a loop structure to supply water from the service reservoirs and balancing reservoirs to consumers. Components A water distribution system consists of pipelines, storage facilities, pumps, and other accessories. Pipelines laid within public righ ...

Edwin Butterworth Mains
Edwin Butterworth Mains (1890–1968) was an American mycologist. He was known for his taxonomic research on the rust fungi ( Pucciniomycetes), the genus '' Cordyceps'', and the earth tongues ( Geoglossaceae). Biography Edwin Butterworth Mains was born on 31 March 1890 in Coldwater, Branch County, Michigan. The son of Benjamin W. and Mary Ann (Butterworth) Mains. Mains began his undergraduate education at Michigan State University in 1909, but transferred to the University of Michigan in 1911. He earned his Ph.D. in botany from the University of Michigan in 1916 under the tutelage of Calvin Henry Kauffman while investigating the parasite-host relationships of various rust fungi. He was appointed Assistant Botanist at the Purdue University Agricultural Experimental Station by Joseph Charles Arthur in 1916.
