Mica Dam
Mica Dam is a hydroelectric embankment dam spanning the Columbia River 135 kilometres north of Revelstoke, British Columbia, Canada. It was built as one of three Canadian projects under the terms of the 1964 Columbia River Treaty and is operated by BC Hydro. Completed in 1973, the Mica powerhouse had an original generating capacity of 1,805 megawatts (MW). Mica Dam, named after the nearby settlement of Mica Creek and its associated stream, in turn named after the abundance of mica minerals in the area, is one of the largest earthfill dams in the world. The reservoir created by the dam is Kinbasket Lake. Water from the dam flows south directly into Revelstoke Lake, the reservoir for the Revelstoke Dam. Mica Dam is the tallest dam in Canada and second tallest in North America after the Chicoasén Dam in Mexico and it is the farthest upstream dam on the Columbia River. The dam's underground powerhouse was the second largest in the world at the time of its construction, and was the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrical Generator
In electricity generation, a generator, also called an ''electric generator'', ''electrical generator'', and ''electromagnetic generator'' is an electromechanical device that converts mechanical energy to electrical energy for use in an external circuit. In most generators which are rotating machines, a source of kinetic power rotates the generator's shaft, and the generator produces an electric current at its output terminals which flows through an external circuit, powering electrical loads. Sources of mechanical energy used to drive generators include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. Generators produce nearly all of the electric power for worldwide electric power grids. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the electricity generation, generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more Electric generator, generators, rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a Electrical conductor, conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, petroleum, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and use of renewable energy, renewables such as solar power, solar, wind power, wind, geothermal power, geothermal, and hydroelectricity, hydroelectric.

Mica Dam Spillway
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into fragile elastic plates. This characteristic is described as ''perfect basal cleavage''. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, and fillers, especially in parts for automobiles, roofing, and in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost". Properties and structure The mica group comprises 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are translucent to opaque w ...

Mica Creek, British Columbia
Mica Creek is a small village in British Columbia, Canada that was used as a base of operations for the construction of the Mica Dam hydroelectric project by BC Hydro in the 1960s and 1970s. It is located 148 km north of Revelstoke, British Columbia on Highway 23 and situated at the convergence of the Revelstoke Lake (the Columbia River) and a stream called Mica Creek. The village is effectively a relocation of Mica, which had been at the confluence of the Columbia and Mica Creek proper. The creek itself was named for the flakes of mica minerals which could be found floating in its waters. The Mica Creek area was one of the foci of the Big Bend Gold Rush of the 1860s. The village of Mica Creek reached its peak population of approximately 4000 people around 1973, at the time of the opening of the Mica Dam. At that time there were quite a number of amenities including a school, church, ski lodge, community center, outdoor swimming pool, police station, fire hall, grocery ...

Arrow Dam
Hugh Keenleyside Dam (formerly known as the High Arrow Dam) is a flood control dam spanning the Columbia River, 12 km (6.5 miles) upstream of the city of Castlegar, British Columbia, Canada. Dam The dam is at the outflow of what was the upper and lower Arrow Lakes; today the two lakes are joined forming one long reservoir extending north to Revelstoke Dam, and contains 8.76 km3 (7.1 MAF) of reservoir volume. The dam is operated by BC Hydro. The long earth fill and concrete dam was built as part of fulfilling Canada's obligations under the Columbia River Treaty, along with the Duncan Dam, both were built to prevent flooding and control the flow of water in the Columbia River for downstream hydroelectric dams. It was commissioned on October 10, 1968, six months ahead of schedule. Immediately downstream of the dam a 185 megawatt (MW) hydroelectric powerhouse, the Arrow Lakes Generating Station, began construction in 1999 and was completed in 2002. The station is owne ...

Duncan Dam
Duncan Dam is a dam spanning the Duncan River (British Columbia), Duncan River in the Provinces and territories of Canada, Canadian province of British Columbia. Duncan Dam was the first dam built to satisfy the Columbia River Treaty, initiated after the 1948 flood along the lower Columbia, which proved fatal at Vanport City, Oregon and other locations. Construction began in 1965, and was completed in 1967. It is an earthfill dam with no power generation facilities. It was built as a storage facility, controlling the flow of water from the Duncan River (British Columbia), Duncan River into the Kootenay Lake reservoir. The reservoir's storage is over 50% greater than Kootenay Lake. The reservoir is usually filled by August. The Duncan river drainage basin is 2,400 square kilometers. The dam regulates 10% of the water in the Kootenay River basin. Duncan Dam and Libby Dam together ensure operational water levels for the Kootenay Canal and Corra Linn Dam projects.

Switchgear
In an electric power system, a switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levels and voltages rapidly escalated, making opening manually operated switches too dangerous for anything other than isolation of a de-energized circuit. Oil-filled switchgear equipment allows arc energy to be contained and safely controlled. By the early 20th century, a switchgear line-up would be a metal-enclosed structure with electrically operated switching elements using oil circuit breakers. Today, oil-filled equipment has largely been replaced by air-blast, vacuum, or SF6 equ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
