An art gallery is a room or a building in which visual art is displayed. In Western cultures from the mid-15th century, a gallery was any long, narrow covered passage along a wall, first used in the sense of a place for art in the 1590s. The long gallery in Elizabethan and Jacobean houses served many purposes including the display of art. Historically, art is displayed as evidence of status and wealth, and for religious art as objects of ritual or the depiction of narratives. The first galleries were in the palaces of the aristocracy, or in churches. As art collections grew, buildings became dedicated to art, becoming the first art museums.

71-552: The Grosvenor Gallery was an art gallery in London founded in 1877 by Sir Coutts Lindsay and his wife Blanche. Its first directors were J. Comyns Carr and Charles Hallé . The gallery proved crucial to the Aesthetic Movement because it provided a home for those artists whose approaches the more classical and conservative Royal Academy did not welcome, such as Edward Burne-Jones and Walter Crane . The gallery

142-447: A bus plus some circuit breakers . The largest transmission substations can cover a large area (several acres/hectares) with multiple voltage levels, many circuit breakers, and a large amount of protection and control equipment ( voltage and current transformers , relays and SCADA systems). Modern substations may be implemented using international standards such as IEC Standard 61850 . A distribution substation transfers power from

213-617: A common component of the infrastructure. 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 larger, smaller generating plants were converted to distribution stations, receiving their energy supply from

284-413: A contractor for actual construction. Major design constraints for construction of substations include land availability and cost, limitations on the construction period, transportation restrictions, and the need to get the substation running quickly. Prefabrication is a common way to reduce the construction cost. For connecting the new substation, a partial outage at another substation may be required, but

355-706: A disconnection of the load supplied by the circuit break from the feeding point. This seeks to isolate the fault point from the rest of the system, and allow the rest of the system to continue operating with minimal impact. Both switches and circuit breakers may be operated locally (within the substation) or remotely from a supervisory control center. With overhead transmission lines , the propagation of lightning and switching surges can cause insulation failures into substation equipment. Line entrance surge arrestors are used to protect substation equipment accordingly. Insulation Coordination studies are carried out extensively to ensure equipment failure (and associated outages )

426-513: A famous libel case, brought by the artist against the critic. Whistler won a farthing in damages. The case made the gallery famous as the home of the Aesthetic movement, which was satirised in Gilbert and Sullivan 's Patience , which includes the line, "greenery-yallery, Grosvenor Gallery". The enterprising art critic Henry Blackburn issued illustrated guides to the annual exhibitions under

497-429: A gallery, a kunsthalle is a facility that hosts temporary art exhibitions however does not possess a permanent collection . The art world comprises everyone involved in the production and distribution of fine art. The market for fine art depends upon maintaining its distinction as high culture , although during recent decades the boundary between high and popular culture has been eroded by postmodernism . In

568-457: A large substation, circuit breakers are used to interrupt any short circuits or overload currents that may occur on the network. Smaller distribution stations may use recloser circuit breakers or fuses for protection of distribution circuits. Substations themselves do not usually have generators, although a power plant may have a substation nearby. Other devices such as capacitors , voltage regulators , and reactors may also be located at

639-422: A larger plant instead of using their own generators. The first substations were connected to only one power station , where the generators were housed, and were subsidiaries of that power station. Substations may be designed and built by a contractor or alternately all phases of its development may be handled by the electrical utility . Most commonly, the utility does the engineering and procurement while hiring

710-522: A long lease such as a renewable 99-year lease, giving the utility company security of tenure . The first step in planning a substation layout is the preparation of a one-line diagram , which shows in simplified form the switching and protection arrangement required, as well as the incoming supply lines and outgoing feeders or transmission lines. It is a usual practice by many electrical utilities to prepare one-line diagrams with principal elements (lines, switches, circuit breakers, transformers) arranged on

781-649: A number of locations. Galleries selling the work of recognized artists may occupy space in established commercial areas of a city. New styles in art have historically been attracted to the low rent of marginal neighborhoods. An artist colony existed in Greenwich Village as early as 1850, and the tenements built around Washington Square Park to house immigrants after the Civil War also attracted young artists and avant-garde art galleries. The resulting gentrification prompted artists and galleries to move to

852-690: A ring bus, double bus, or so-called "breaker and a half" setup can be used, so that the failure of any one circuit breaker does not interrupt power to other circuits, and so that parts of the substation may be de-energized for maintenance and repairs. Substations feeding only a single industrial load may have minimal switching provisions, especially for small installations. Because of the risk of electrical shock, substations are inherently dangerous to electrical workers. To mitigate this hazard, substations are designed with various safety features. Live conductors and bare equipment are kept separate, either with protected equipment, or using screens or distance. Based on

923-679: A substation. Substations may be on the surface in fenced enclosures, underground, or special-purpose buildings. High-rise buildings may have several indoor substations. Indoor substations are usually found in urban areas to reduce the noise from transformers, improve appearance, or protect switchgear from extreme climate or pollution. Substations often use busbars as conductors between electrical equipment. Busbars may be aluminum tubing 3–6 inches (76–152 mm) thick, or else wires (strain bus). Outdoor, above-ground substation structures include wood pole, lattice metal tower, and tubular metal structures, although other variants are available. Where space

994-422: A transmission line or a transformer. To maintain reliability of supply, companies aim at keeping the system up and running while performing maintenance. All work to be performed, from routine testing to adding entirely new substations, should be done while keeping the whole system running. Unplanned switching events are caused by a fault in a transmission line or any other component, for example: The function of

1065-657: Is a unique commodity, the artist has a monopoly on production, which ceases when the artist either dies or stops working. Some businesses operate as vanity galleries , charging artists a fee to exhibit their work. Lacking a selection process to assure the quality of the artworks, and having little incentive to promote sales, vanity galleries are avoided as unprofessional. Some non-profit organizations or local governments host art galleries for cultural enrichment and to support local artists. Non-profit organizations may start as exhibit spaces for artist collectives , and expand into full-fledged arts programs. Other non-profits include

1136-602: Is aimed at minimizing cost while ensuring power availability and reliability, and enabling changes to the substation in the future. Substations may be built outdoors, indoors, or underground or in a combination of these locations. Selection of the location of a substation must consider many factors. Sufficient land area is required for installation of equipment with necessary clearances for electrical safety, and for access to maintain large apparatus such as transformers. The site must have room for expansion due to load growth or planned transmission additions. Environmental effects of

1207-465: Is common in the area. The output is a number of feeders. Distribution voltages are typically medium voltage, between 2.4 kV and 33 kV, depending on the size of the area served and the practices of the local utility. The feeders run along streets overhead (or underground, in some cases) and power the distribution transformers at or near the customer premises. In addition to transforming voltage, distribution substations also isolate faults in either

1278-402: Is minimal. Once past the switching components, the lines of a given voltage connect to one or more buses . These are sets of busbars , usually in multiples of three, since three-phase electrical power distribution is largely universal around the world. The arrangement of switches, circuit breakers, and buses used affects the cost and reliability of the substation. For important substations

1349-474: Is necessary to work on parts of the substation while energized, but employees must maintain a safe distance of at least 3 metres (9.8 ft). The aim to reduce substation footprints comes into conflict with ease of maintenance enhanced by including gaps where employees can safely work. Underneath a substation, a mat or grid of conductors laid around 0.5 or 0.6 metres (1 ft 8 in or 2 ft 0 in) underground provides grounding . This grid, which

1420-472: Is plentiful and appearance of the station is not a factor, steel lattice towers provide low-cost supports for transmission lines and apparatus. Low-profile substations may be specified in suburban areas where appearance is more critical. Indoor substations may be gas insulated substations (GIS) (at high voltages, with gas insulated switchgear), or use metal-enclosed or metal-clad switchgear at lower voltages. Urban and suburban indoor substations may be finished on

1491-563: Is that while maintaining their urban establishments, galleries also participate in art fairs such as Art Basel and Frieze Art Fair . Art galleries are the primary connection between artists and collectors . At the high end of the market, a handful of elite auction houses and dealers sell the work of celebrity artists; at the low end artists sell their work from their studio, or in informal venues such as restaurants. Point-of-sale galleries connect artists with buyers by hosting exhibitions and openings. The artworks are on consignment, with

1562-451: Is typically copper although it may be galvanized iron in some countries, is used to ground circuits that are being worked on to prevent accidental re-energization while workers are in contact with a de-energized circuit. Often, earth rods are driven deeper into the ground from the grounding grid for lower resistance grounding, and may be surrounded by bentonite or marconite to further reduce resistance and ensure effective grounding for

1633-410: Is used as a protection device to interrupt fault currents automatically, and may be used to switch loads on and off, or to cut off a line when power is flowing in the 'wrong' direction. When a large fault current flows through the circuit breaker, this is detected through the use of current transformers . The magnitude of the current transformer outputs may be used to trip the circuit breaker resulting in

1704-510: Is used to refer to establishments with distinct social and economic functions, both public and private. Institutions that preserve a permanent collection may be called either "gallery of art" or "museum of art". If the latter, the rooms where art is displayed within the museum building are called galleries. Art galleries that do not maintain a collection are either commercial enterprises for the sale of artworks, or similar spaces operated by art cooperatives or non-profit organizations . As part of

1775-496: The Middle Ages that preceded, painters and sculptors were members of guilds, seeking commissions to produce artworks for aristocratic patrons or churches. The establishment of academies of art in the 16th century represented efforts by painters and sculptors to raise their status from mere artisans who worked with their hands to that of the classical arts such as poetry and music, which are purely intellectual pursuits. However,

1846-475: The Museum of Modern Art and National Museum of Western Art ). However, establishments that display art for other purposes, but serve no museum functions, are only called art galleries. The distinctive function of a museum is the preservation of artifacts with cultural, historical, and aesthetic value by maintaining a collection of valued objects. Art museums also function as galleries that display works from

1917-543: The Pre-Raphaelite Brotherhood . But it also featured work by others that were widely shown elsewhere, including the Royal Academy, such as Lawrence Alma-Tadema , Edward John Poynter and James Tissot . In 1877 John Ruskin visited the gallery to see work by Burne-Jones. An exhibition of paintings by James McNeill Whistler was also on display. Ruskin's savage review of Whistler's work led to

1988-497: The art world , art galleries play an important role in maintaining the network of connections between artists, collectors, and art experts that define fine art . The terms 'art museum' and 'art gallery' may be used interchangeably as reflected in the names of institutions around the world, some of which are called galleries (e.g. the National Gallery and Neue Nationalgalerie ), and some of which are called museums (e.g.

2059-416: The microprocessor made for an exponential increase in the number of points that could be economically controlled and monitored. Today, standardized communication protocols such as DNP3 , IEC 61850 and Modbus , to list a few, are used to allow multiple intelligent electronic devices to communicate with each other and supervisory control centers. Distributed automatic control at substations is one element of

2130-465: The Czech Republic, where power is collected from nearby lignite -fired power plants. If no transformers are required for increasing the voltage to transmission level, the substation is a switching station. Converter substations may be associated with HVDC converter plants, traction current , or interconnected non-synchronous networks. These stations contain power electronic devices to change

2201-636: The Grosvenor Gallery name was revived twice by unrelated ventures: Upon returning from the Paris Exhibition of 1882, the Earl of Crawford recommended that Lindsay install electric lighting in the gallery. In 1883, two Marshall engines, each belted to a Siemens alternator , were installed in a yard behind the gallery. The installation was a success, and neighbours began requesting a supply. Lindsay, Crawford and Lord Wantage then set up

2272-769: The Sir Coutts Lindsay Co. Ltd., and in 1885 constructed the Grosvenor Power Station. This was constructed under the gallery and had a capacity of 1,000 kilowatts . The station supplied an area reaching as far north as Regent's Park , the River Thames to the south, Knightsbridge to the west and the High Court of Justice to the east. However the system caused a lot of trouble, so much so that Sebastian Ziani de Ferranti gave advice as to how to resolve it in 1885; by January 1886 Farranti

2343-413: The adjacent neighborhood "south of Houston" ( SoHo ) which became gentrified in turn. Attempting to recreate this natural process, arts districts have been created intentionally by local governments in partnership with private developers as a strategy for revitalizing neighborhoods. Such developments often include spaces for artists to live and work as well as galleries. A contemporary practice has been

2414-591: The amps exceed a certain amount over a period of time. Reclosers will attempt to re-energize the circuit after a delay. If unsuccessful for a few times, the recloser will have to be manually reset by an electrical worker. Capacitor banks are used in substations to balance the lagging current draw from inductive loads (such as motors, transformers, and some industrial equipment) with their reactive load . Additional capacitor capacity may be needed if dispersed generation (such as small diesel generators, rooftop photovoltaic solar panels , or wind turbines ) are added to

2485-412: The art market. Art dealers, through their galleries, have occupied a central role in the art world by bringing many of these factors together; such as "discovering" new artists, promoting their associations in group shows, and managing market valuation. Exhibitions of art operating similar to current galleries for marketing art first appeared in the early modern period , approximately 1500 to 1800 CE. In

2556-549: The artist and the gallery splitting the proceeds from each sale. Depending upon the expertise of the gallery owner and staff, and the particular market, the artwork shown may be more innovative or more traditional in style and media. Galleries may deal in the primary market of new works by living artists, or the secondary markets for works from prior periods owned by collectors, estates, or museums. The periods represented include Old Masters , Modern (1900–1950), and contemporary (1950–present). Modern and contemporary may be combined in

2627-409: The arts as part of other missions, such as providing services to low-income neighborhoods. Historically, art world activities have benefited from clustering together either in cities or in remote areas offering natural beauty. The proximity of art galleries facilitated an informal tradition of art show openings on the same night, which have become officially coordinated as " first Friday events " in

2698-456: The case of historical works, or Old Masters this distinction is maintained by the work's provenance ; proof of its origin and history. For more recent work, status is based upon the reputation of the artist. Reputation includes both aesthetic factors; art schools attended, membership in a stylistic or historical movement, the opinions of art historians and critics; and economic factors; inclusion in group and solo exhibitions and past success in

2769-447: The category of Post-war art; while contemporary may be limited to the 21st century or "emerging artists". An enduring model for contemporary galleries was set by Leo Castelli . Rather than simply being the broker for sales, Castelli became actively involved in the discovery and development of new artists, while expecting to remain an exclusive agent for their work. However he also focused exclusively on new works, not participating in

2840-587: The complexity of distribution networks grew, it became economically necessary to automate supervision and control of substations from a centrally attended point, to allow overall coordination in case of emergencies and to reduce operating costs. Early efforts to remote control substations used dedicated communication wires, often run alongside power circuits. Power-line carrier , microwave radio , fiber optic cables as well as dedicated wired remote control circuits have all been applied to Supervisory Control and Data Acquisition (SCADA) for substations. The development of

A switching station may also be known as a switchyard, and these are commonly located directly adjacent to or nearby a power station . In this case the generators from the power station supply their power into the yard onto the generator bus on one side of

2982-416: The equipment used to monitor, control, and protect the rest of the substation equipment. It often contains protective relays, meters, breaker controls, communications, batteries, and recorders that save detailed data about substation operations, particularly when there is any unusual activity, to help reconstruct what happened after the fact. These control rooms typically are heated and air conditioned to ensure

3053-531: The first indications of modern values regarding art; art as an investment versus pure aesthetics, and the increased attention to living artists as an opportunity for such investment. Commercial galleries owned or operated by an art dealer or "gallerist" occupy the middle tier of the art market , accounting for most transactions, although not those with the highest monetary values. Once limited to major urban art worlds such as New York, Paris and London, art galleries have become global. Another trend in globalization

3124-425: The frequency of current, or else convert from alternating to direct current or the reverse. Formerly rotary converters changed frequency to interconnect two systems; nowadays such substations are rare. A switching station is a substation without transformers and operating only at a single voltage level. Switching stations are sometimes used as collector and distribution stations. Sometimes they are used for switching

3195-408: The jurisdiction or company, there are safety standards with minimum required clearance between different live equipment or conductors or between live metal and the ground, which often varies with higher clearance being required for higher voltages because of the greater ability to generate flashover . To this is added the necessary space for employees to work safely and vehicles to pass. Sometimes it

3266-590: The lifetime of the substation. Above ground, the grounding conductors may be steel, aluminum, or copper. They must be thick enough to carry the expected current of a fault for 1-3 seconds and remain undamaged. Substation fences, typically at least 2 metres (6 ft 7 in) in height, both protect the public from electrical hazards and also protect the substation from vandalism. Internal fences can also be incorporated to protect employees from areas that are unsafe when energized. Substations generally have switching, protection and control equipment, and transformers. In

3337-411: The low-voltage side. More typical distribution substations have a switch, one transformer, and minimal facilities on the low-voltage side. In distributed generation projects such as a wind farm or photovoltaic power station , a collector substation may be required. It resembles a distribution substation although power flow is in the opposite direction, from many wind turbines or inverters up into

3408-456: The museum's own collection or on loan from the collections of other museums. Museums might be in public or private ownership and may be accessible to all or have restrictions on access. Although primarily concerned with visual art , art museums are often used as a venue for other cultural exchanges and artistic activities where the art object is replaced by practices such as performance art , dance, music concerts, or poetry readings. Similar to

3479-411: The outside so as to blend in with other buildings in the area. A compact substation is generally an outdoor substation built in a metal enclosure, in which each item of the electrical equipment is located very near to each other to create a relatively smaller footprint size of the substation. High-voltage circuit breakers are commonly used to interrupt the flow of current in substation equipment. At

3550-407: The page similarly to the way the apparatus would be laid out in the actual station. In a common design, incoming lines have a disconnect switch and a circuit breaker . In some cases, the lines will not have both, with either a switch or a circuit breaker being all that is considered necessary. A disconnect switch is used to provide isolation, since it cannot interrupt load current. A circuit breaker

3621-471: The public exhibition of art had to overcome the bias against commercial activity, which was deemed beneath the dignity of artists in many European societies. Commercial art galleries were well-established by the Victorian era , made possible by the increasing number of people seeking to own objects of cultural and aesthetic value. At the end of the 19th and the beginning of the 20th century there were also

3692-661: The public grid. Sometimes they are also transmission substations or collector substations if the railway network also operates its own grid and generators to supply the other stations. A mobile substation is a substation on wheels, containing a transformer, breakers and buswork mounted on a self-contained semi-trailer , meant to be pulled by a truck . They are designed to be compact for travel on public roads, and are used for temporary backup in times of natural disaster or war . Mobile substations are usually rated much lower than permanent installations, and may be built in several units to meet road travel limitations. Substation design

3763-411: The reliable operation of this equipment. Additional equipment is necessary to handle power surges associated with intermittent renewable energy such as dispersed generation from wind or solar. Most transformers lose between 5 and 1.5 percent of their input as heat and noise. Iron losses are no-load and constant whenever the transformer is energized, while copper and auxiliary losses are proportionate to

3834-434: The resale of older work by the same artists. All art sales after the first are part of the secondary market, in which the artist and the original dealer are not involved. Many of these sales occur privately between collectors, or works are sold at auctions. However some galleries participate in the secondary market depending upon the market conditions. As with any market, the major conditions are supply and demand. Because art

3905-399: 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

3976-430: The square of the current. Auxiliary losses are due to running fans and pumps which is noisy when the transformer is operating at maximum capacity. To reduce noise, enclosures are often built around the transformer and can also be added after the substation is built. Oil-based transformers are often built with bunded areas to prevent the escape of flaming or leaking oil. Fire separation areas or firewalls are built around

4047-451: The substation must be considered, such as drainage , noise and road traffic effects. The substation site must be reasonably central to the distribution area to be served. The site must be secure from intrusion by passers-by, both to protect people from injury by electric shock or arcs, and to protect the electrical system from misoperation due to vandalism. If not owned and operated by a utility company, substations are typically occupied on

4118-454: The substation where electrical energy is being converted to heat, which indicates a problem and can cause additional damage from the high heat. Dissolved gas analysis can tell when an oil-insulated transformer needs to have the oil filtered or replace, and also detect other issues. Early electrical substations required manual switching or adjustment of equipment, and manual collection of data for load, energy consumption, and abnormal events. As

4189-554: The switching station is to isolate the faulty portion of the system in the shortest possible time. De-energizing faulty equipment protects it from further damage, and isolating a fault helps keep the rest of the electrical grid operating with stability. Electrified railways also use substations, often distribution substations. In some cases a conversion of the current type takes place, commonly with rectifiers for direct current (DC) trains, or rotary converters for trains using alternating current (AC) at frequencies other than that of

4260-436: The system. Capacitors can reduce the current in wires, helping stem system losses from voltage drop or enabling extra power to be sent through the conductors. Capacitors may be left on in response to constant inductive load or turned on when inductive load is increased, such as in the summer for air conditioners . The switching may be remote and can be done manually or automatically. Larger substations have control rooms for

4331-466: The time of interruption, current could be normal, too high due to excessive load, unusual due to a fault, or tripped by protective relays prior to anticipated trouble. The most common technologies to extinguish the power arc from separating the conductors in the breaker include: Reclosers are similar to breakers, and can be cheaper because they do not require separate protective relays. Often used in distribution, they often are programmed to trip when

4402-427: The title Grosvenor Notes (1877–82). In 1888, after a disagreement with Lindsay, Comyns Carr and Hallé resigned from the gallery to found the rival New Gallery , capturing Burne-Jones and many of the Grosvenor Gallery's other artists. The break-up of his marriage, financial constraints and personal conflicts forced Lindsay out of the gallery, which was taken over by his estranged wife. After its closure in 1890

4473-429: The transformer to stop the spread of fire. Firefighting vehicles are allowed a path to access the area. Maintenance of substations involves inspections, data collection and analysis, and routine scheduled work. Using methods such as infrared scanning and dissolved gas analysis, it can be predicted when the substation will need maintenance and predict dangers before they materialize. Infrared technology finds hot spots in

4544-712: The transmission grid. Usually for economy of construction the collector system operates around 35 kV, although some collector systems are 12 kV, and the collector substation steps up voltage to a transmission voltage for the grid. The collector substation can also provide power factor correction if it is needed, metering, and control of the wind farm. In some special cases a collector substation can also contain an HVDC converter station. Collector substations also exist where multiple thermal or hydroelectric power plants of comparable output power are in proximity. Examples for such substations are Brauweiler in Germany and Hradec in

4615-401: The transmission or distribution systems. Distribution substations are typically the points of voltage regulation , although on long distribution circuits (of several miles/kilometers), voltage regulation equipment may also be installed along the line. The downtown areas of large cities feature complicated distribution substations, with high-voltage switching, and switching and backup systems on

4686-454: The transmission system to the distribution system of an area. It is uneconomical to directly connect electricity consumers to the main transmission network, unless they use large amounts of power, so the distribution station reduces voltage to a level suitable for local distribution. The input for a distribution substation is typically at least two transmission or sub-transmission lines. Input voltage may be, for example, 115 kV, or whatever

4757-526: The use of vacant commercial space for art exhibitions that run for periods from a single day to a month. Now called "popup galleries", a precursor was Artomatic which had its first event in 1999 and has occurred periodically to the present, mainly in the Washington metro area . Electrical substation A substation is a part of an electrical generation , transmission , and distribution system. Substations transform voltage from high to low, or

4828-826: The utility often tries to minimize downtime. Substations typically serve at least one of the following purposes: A transmission substation connects two or more transmission lines. The simplest case is where all transmission lines have the same voltage. In such cases, substation contains high-voltage switches that allow lines to be connected or isolated for fault clearance or maintenance. A transmission station may have transformers to convert between two transmission voltages, voltage control / power factor correction devices such as capacitors, reactors or static VAR compensators and equipment such as phase shifting transformers to control power flow between two adjacent power systems. Transmission substations can range from simple to complex. A small "switching station" may be little more than

4899-462: The yard, and the transmission lines take their power from a Feeder Bus on the other side of the yard. An important function performed by a substation is switching , which is the connecting and disconnecting of transmission lines or other components to and from the system. Switching events may be planned or unplanned. A transmission line or other component may need to be de-energized for maintenance or for new construction, for example, adding or removing
