Transcontinental Gas Pipe Line Company
Transcontinental Gas Pipe Line Company, known as Transco, is an American natural gas pipeline company owned by Williams that runs from Texas to New York.
Transformer
A transformer, also called an electrical transformer, is a static device that transfers AC electric energy between circuits by magnetic induction, changing voltage levels to transmit power efficiently.
Transformer differential protection
Transformer differential protection is a unit protection scheme for power transformers that compares incoming and outgoing currents and trips when the difference indicates an internal fault.
Transformer oil
Transformer oil, also called insulating oil, is the liquid used inside transformers to provide electrical insulation and transfer heat from the core and windings to the cooling system.
Transformer types
Transformer types are the classes of electrical transformers, distinguished by function, winding and core construction, and insulation and cooling, including distribution, power, instrument, and autotransformers.
Transformerless inverter
A transformerless inverter is a DC-to-AC converter used mainly in photovoltaic systems that feeds solar power into the grid without an isolation transformer, gaining efficiency and cutting cost and weight while requiring leakage-current protection.
Transgaz (Romania)
Transgaz is the Romanian national gas transmission company, the only licensed transmission system operator in Romania. Created in 2000 from Romgaz, it also operates Moldova's gas transmission system through its subsidiary Vestmoldtransgaz.
Transgrid
Transgrid is the privately held company that operates the high voltage electricity transmission network in New South Wales and the Australian Capital Territory, covering about 11,500 kilometers of lines.
Transient Reactor Test Facility
The Transient Reactor Test Facility (TREAT) is an air-cooled test reactor at Idaho National Laboratory that simulates reactor accidents in fuel samples; built by Argonne, it ran from 1959 to 1994 and restarted in 2017.
Transient recovery voltage
Transient recovery voltage (TRV) is the voltage that appears across a circuit breaker's terminals immediately after it interrupts a current, largely determining whether the breaker can clear a fault.
Transient stability
Transient stability, a branch of rotor angle stability also called large-disturbance angular stability, is a power system's ability to maintain synchronism through a severe disturbance, such as a transmission-line short circuit, and regain equilibrium afterward.
Transient stability analysis
Transient stability analysis is a power systems engineering method that determines whether a grid's synchronous generators remain in synchronism after a large disturbance, such as a short circuit.
Transient testing
Transient testing is an experimental nuclear engineering method that subjects reactor fuels and materials to short bursts of intense neutron flux, studying behavior under accident-like conditions.
Transitgas Gas Pipeline
The Transitgas pipeline is a 292-kilometer natural gas pipeline in Switzerland running from Wallbach to the Gries Pass, carrying about 70% of Swiss gas imports.
Transition Pathway Initiative
The Transition Pathway Initiative (TPI) is an asset-owner-led initiative, launched in 2017, that publishes free assessments of how listed companies are preparing for the low-carbon transition.
Transition piece
A transition piece is the steel structure connecting an offshore wind turbine's tower to its foundation, transferring loads while carrying boat landings, ladders, platforms, and cable routing.
Transition-metal dissolution and crossover
Transition-metal dissolution and crossover is a lithium-battery degradation process in which manganese, nickel, and cobalt ions leach from the cathode and deposit on the anode.
Transmission Company of Nigeria
The Transmission Company of Nigeria (TCN) is the state-owned company that owns and operates Nigeria's national electricity transmission grid, created in 2005 from the unbundled PHCN.
Transmission tower
A transmission tower, also known as an electric pylon or by the German name Hochspannungsmast, is a tall structure, usually a steel lattice, that carries high-voltage conductors of an overhead transmission line.
Transmix
Transmix is the interface mixture that forms in a multiproduct petroleum pipeline where adjacent batches of dissimilar products, like gasoline and diesel, mix at their boundary and cannot be sold as is.
Transneft
Transneft (Транснефть) is a Russian state-controlled company with a monopoly on crude oil pipeline transport, moving more than 83% of Russian oil across the world's largest pipeline network.
TransnetBW
TransnetBW GmbH is the transmission system operator for the German state of Baden-Württemberg, operating its extra-high-voltage grid as one of four German TSOs and majority owned by EnBW.
Transocean
Transocean Ltd. is a Swiss offshore contract drilling company, headquartered in Steinhausen and listed on the New York Stock Exchange as RIG, operating 27 mobile drilling units.
Transocean Barents
Transocean Barents, originally named Aker Barents, is a sixth-generation, harsh-environment semi-submersible drilling rig built in 2009 to drill deepwater wells on the Norwegian continental shelf.
Transparent solar module
A transparent solar module is a photovoltaic module that generates electricity while transmitting visible light, letting windows, building facades, and vehicle glazing produce power without blocking the view.
Transpired solar collector
A transpired solar collector is a solar air-heating device in which a dark, perforated metal sheet mounted on a building wall preheats ventilation air, patented as SolarWall in the late 1980s.
TransSakhalin Gas Pipeline System
TransSakhalin Gas Pipeline System is the twin oil and gas pipeline network of the Sakhalin-2 project on Sakhalin Island, running about 800 km from northern offshore platforms to Prigorodnoye, which has Russia's first LNG plant.
Transuranic waste
Transuranic waste (TRU waste) is radioactive waste containing alpha-emitting elements heavier than uranium, mostly contaminated clothing, tools, and debris from the US nuclear defense program since the 1940s.
Transwestern Pipeline
Transwestern Pipeline is an interstate natural gas pipeline system in the central and southwestern United States, owned by Energy Transfer LP. Built in 1959 and 1960, it runs about 2,700 miles.
Trash rack
A trash rack is an array of parallel bars installed at a hydropower, pump, or spillway intake to block debris while water passes to turbines, often diverting fish.
