In 1896, Jean-Baptiste Frégault bought the North Shore Power Company and buy production rights on the Great Waterfall near Saint-Narcisse. There he built a hydroelectric plant and a high-voltage line of 29 km, the first of the British Empire. The plant was expanded in 1905. In 1907, it was sold to the Shawinigan Water and Power Company.

On May 1, the EGPGC struck again with eight bombs, in banks of A Coruña, Compostela, Vigo, Betanzos and As Pontes de García Rodríguez, causing serious material damage. The attack was claimed by the group two days later. On 12 November, the EGPGC blew a tower of a high-voltage line in Matamá (Vigo). Another bomb against a similar infrastructure was placed two days later in Lugo.

The first turbine will be in operation by 2011. The power plant will take place in Nyírtass, 2,000-dwellers located town next to the Ukrainian border. The construction gives job for 3,000 people. A former high voltage line help to place the power plant there, because since the 1970s Ukraine was a large electricity supplier of Hungary through the Albertirsa- Zahidnoukrainska 750 kV transmission line.

The station is the largest one contributing to peak consumption in the Unified Energy Systems of Russia. More than 70% of generated electrical power goes to Rusal's four smelters in Siberia. In years of heavy rainfall, about 1,600–2,000 GWh are lost due to lack of high-voltage line transmission capacity, and some water bypasses the turbines. To avert this, a new aluminium plant was started on 15 December 2006.

Technologically the station broke much new ground. In 1959 a new Moscow-Stalingrad 500 kV high voltage line power came into operation. Several years later, for the first time in the world, an experimental 800 kV DC line, Donbas to Volgograd, was successfully tested and later became operational. During the 1960s and 1970s several new types of electrotechnical and hydromechanical machines were tested for future Siberian and foreign stations.

On 10 July 2006, the Council of State annulled the declaration of public use of a project by EDF relating to a proposed high- voltage line which would have had to pass through the Verdon Gorge. This decision ended 23 years of struggle by public groups and associations of environmental defence to preserve a site of exceptional natural interest, of which a part contains protected animal and plant species.

Wave traps are used in switchyard of most power stations to prevent carrier from entering the station equipment. Each wave trap has a lightning arrester to protect it from surge voltages. A coupling capacitor is used to connect the transmitters and receivers to the high voltage line. This provides low impedance path for carrier energy to HV line but blocks the power frequency circuit by being a high impedance path.

The opponents went to court to quash the Order in Council authorizing the power line. Construction work resumed after the National Assembly passed a law retroactively approving the work done in the immediate aftermath of the ice storm, but it also required public hearings on the remaining projects. Construction of the Hertel-Des Cantons high voltage line was properly approved in July 2002 and commissioned a year later.

There are significant deposits of gypsum and lime in the rural community, which are mined in the traditional manner. The main source of energy for the population is firewood and it is used for cooking. Timber needs to be imported to a large extent from the neighboring countries. The predominant form of artificial lighting are kerosene lamps, since a high- voltage line from nearby Nigeria was passed only to the village of Laba.

Four nearby electricity generating stations were disabled by the explosion, and the effects of the blast were felt up to 30 miles away. A high-voltage line running adjacent to the plant and over the Missouri River was damaged, disrupting power in the neighboring state of Nebraska. Two 15,000-ton refrigerated ammonia storage tanks were ruptured, releasing liquid ammonia and ammonia vapors which forced the evacuation of 1,700 residents from the surrounding area.

For nearly eleven months, Opie and Anthony was the only show on High Voltage. At the end of their live show, the replay of the show from that morning would begin immediately after. In March 2005, the show held "auditions" for other radio personalities to showcase their programs for the possible addition to the High Voltage line-up. These included The Hill-Man Morning Show from WAAF in Boston, and Loren and Wally, from WROR-FM in Boston.

In 1969 the original long 138,000 Volt line was the longest undersea high voltage line in the world. The existing cables are joined at the oil-fired electric generating substation on Manresa Island in Norwalk Harbor. From there, they cross under Norwalk Harbor and Long Island Sound to connect at the Long Island Power Authority’s substation in the village of Northport, New York. The three new long cables were buried at least one fathom (2 m) below the Sound’s bottom.

The hydroelectric power station of Saint-Narcisse was built between 1895 and 1897 to harness the great falls of the Batiscan River. This plant helped build the first high voltage line of the British Empire and it linked Saint-Narcisse to Trois-Rivières. Electricity Saint-Narcisse fed the electrical distribution system of the city of Trois-Rivières, including street lighting. From the village of Saint-Narcisse, visitors access to the barrage of Batiscan River using the Route 361 on about , then just follow road signs of Hydro-Quebec.

In January 2017, the owners of Lake Turkana Wind Power Station started to bill the Kenya Power Company a monthly "capacity charge" of KSh700 million (approx. US$7 million), for power produced by the power station that cannot be evacuated due to lack a high voltage line to transmit it to the substation at Suswa. Following negotiations, in September 2017, the government of Kenya agreed to pay the developers of Lake Turkana Wind Power Station, a total of Sh5.7 billion (approx. US$55.83 million), in monthly installments, spread over a six year period.

It is proposed to have a spur from Buronga to Red Cliffs in Victoria. Assessment of the Regulatory Investment Test for Transmission (RIT-T) began in June 2019. The link endpoints are at Robertstown in South Australia where major transmission lines connect to the north and south of the state, and Wagga Wagga, the furthest west in New South Wales that the high voltage lines reach. The new high-voltage line is expected to improve the feasibility of more solar and wind farms in the areas traversed by the line.

Possible scenario of the GRAND Canal scheme, showing the initial water capture and diversion into Lake Huron. Since 1971, the government of Quebec has built hydroelectric dams on rivers in the James Bay watershed, notably La Grande and Eastmain rivers. Built between 1974 and 1996, the James Bay Project now has a combined generating capacity of 16,021 MW and produces about 83 billion kWh of electricity each year, about half of Quebec's consumption. Power is also exported to the United States via a direct transmission high voltage line.

The reforms implemented in the 1990s led to high investment, which allowed for a 75% increase in generation capacity, resulting in the decrease of prices in the wholesale market from US$40/MW·h in 1992 to US$23/MW·h in 2001. However, the reforms failed to deliver the necessary increase in transmission capacity. Only one relevant project, the addition of the 1,300 km high voltage line between Comahue and Buenos Aires, was built in the 1990s. Distribution networks were also renovated and expanded, which resulted in efficiency and quality improvements.

The aforementioned effort to restart the private production of airplanes could not be realized in Communist Poland. The machine tools and accrued tools and measuring instruments ended being taken over and then sold at auction by the government. Meanwhile, In 1945, for the Ministry of Communications, he projected the construction of the high voltage line between Otwock and Miłosna suburbs. During 1945 and 1946, Chyliński took part in an open competition of the Civil Aviation Department for developing a training glider, in which he won the first prize with his project of a motor glider, the HWL Pegaz.

At $0.03/kWh, a common off-peak high-voltage line rate in the United States, hydrogen costs $1.50 per kilogram for the electricity, equivalent to $1.50/gallon for gasoline. Other costs include the electrolyzer plant, hydrogen compressors or liquefaction, storage and transportation. Hydrogen can also be produced from aluminum and water by stripping aluminum's naturally-occurring aluminum oxide barrier and introducing it to water. This method is beneficial because recycled aluminum cans can be used to generate hydrogen, however systems to harness this option have not been commercially developed and are much more complex than electrolysis systems.

The first and only modified CD player introduced by the company was the CD-1 based on the Philips Magnavox line of CD players. The company engineers chose the Magnavox unit because the belief at the time was it sounded better to its only rival in the marketplace, the Sony. Inside the CD 1 PS engineers added a discrete high voltage line stage and power supply, replacing the NE 5532 op amps used as the output amplification stage of the Magnavox. This unit was a stopgap product designed to get the company "in the game" of this new format that would someday challenge vinyl, the company's core products addressed.

As it is a vital decision for the town, wide public consultations were carried out in 2008–2010 by both the town authorities and the Government of Greenland in order to address potential environmental and social concerns. The Sisimiut Hydro Power Plant is located north of the town. The plant has two turbines providing 15 megawatts of power and the electricity from the plant is transferred to Sisimiut by a long high voltage line. The former Colonial Manager's Home, now part of the Sisimiut Museum Although rainfall is low, Sismiut has abundant natural supplies of fresh, drinkable surface water, collected from a reservoir under Alanngorsuaq.

Electronically, the train is actually two identical half-trains of four coaches each, each with an independent power system, apart from the active pantograph (only a single pantograph is raised on AC-fed rail lines) and a high voltage line along the entire length of the 8-car train. The train's capacity of 404 passengers is split between three classes; with two coupled 8-car trains total capacity is therefore 808 passengers. In the end coaches (driving trailers), glass screens separate the driver and passengers, and allow passengers the same views as the driver, just as in the ICE 3 and other Velaros. The driver can turn these opaque if necessary or preferred.

Investigators believe that the failure of a badly maintained steel hook holding up a high voltage line was a key cause of the fire. A PG&E; report to CPUC on December 11, 2018 said that "it had found a hook designed to hold up power lines on the tower was broken before the fire, and that the pieces showed wear." A distribution line in Concow malfunctioned a half hour later, which was considered as a possible second ignition source. On November 11 PG&E; employees saw bullets and bullet holes on pole equipment from the Big Bend distribution line affected by that outage, and downed wires, damaged poles and fallen trees about two thirds of a mile away.

Filtering devices are applied at substations to prevent the carrier frequency current from being bypassed through the station apparatus and to ensure that distant faults do not affect the isolated segments of the PLC system. These circuits are used for control of switchgear, and for protection of transmission lines. For example, a protective relay can use a PLC channel to trip a line if a fault is detected between its two terminals, but to leave the line in operation if the fault is elsewhere on the system. On some powerlines in the former Soviet Union, PLC-signals are not fed into the high voltage line, but in the ground conductors, which are mounted on insulators at the pylons.

On the night of 16/17 April 1941, a Luftwaffe air raid had destroyed several trains, halted underground services and prompted the evacuation of the War Office after an unexploded bomb was found on Hungerford Bridge, the main bridge into Charing Cross Station. Gidden found the mine had come to rest across the railway's live high voltage line and that he would have to turn it over to reach the fuse. Working from dawn, it took six hours for him to make the device safe, at times having to ease the distorted casing back with a hammer and chisel where it had melted onto the live 'third rail'. Notice of the award appeared in the London Gazette of 9 June 1942.

Digging equipment (either hand tools or machine driven) that contacts a buried cable may energize piping or the ground in the area, resulting in electrocution of nearby workers. A fault in a high-voltage transmission line or substation may result in high currents flowing along the surface of the earth, producing an earth potential rise that also presents a danger of electric shock. For high voltage and extra-high voltage transmission lines, specially trained personnel use "live line" techniques to allow hands-on contact with energized equipment. In this case the worker is electrically connected to the high-voltage line but thoroughly insulated from the earth so that he is at the same electrical potential as that of the line.

After two consecutive decades of sustained growth, the late 1980s and the 1990s were much more difficult for Hydro-Québec, especially on the environmental front. A new hydroelectric development and the construction of a direct current high voltage line built to export power to New England faced strong opposition from the Crees as well as environmental groups from the US and Canada. In order to export power from the James Bay Project to New England, Hydro-Québec planned the construction of a long direct current power line, with a capacity of 2,000 megawatts, the so- called "Réseau multiterminal à courant continu" (English: Direct Current Multiterminal Network). Construction work on the line went without a problem except at the location where the power line had to cross the Saint Lawrence River, between Grondines and Lotbinière.

The filters deliver a reactive power of 95 Mvar. Additional 95 Mvar reactive power is delivered by a capacitor bank. Each station's static inverter, which is switched as a 12-pulse thyristor bridge, consists of 792 thyristors arranged in three high towers installed in a valve hall. The SwePol link was inaugurated in 2000 and can transmit up to 600 MW power at a voltage of 450 kV. It was initially owned and maintained by SwePol Link AB, a company jointly owned by the state-owned Swedish power company Svenska Kraftnät (51%), Vattenfall (16%), and Polish transmission system operator PSE-Operator (33%), but the company was liquidated and the cable was acquired by Svenska Kraftnät for the Swedish and PSE-Operator for the Polish part of the cable. Since coming online, 11 instances of cable damage have occurred: one on the high voltage line and 10 on the return cable.
