Transesterification

energy

In organic chemistry, transesterification is the process of exchanging the organic group R″ of an ester with the organic group R′ of an alcohol as is used in the production of biodiesel.

Transfer switch

energy

A switch used to transfer an electrical load from one source to another. Utilised when a source has failed and can include manual or automatic switching.

Transformer

energy

A passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.

Transformer fast depressurization systems

energy

Passive mechanical systems designed to depressurize the transformer a few milliseconds after the occurrence of an electrical fault. Those system prevent any fire by avoiding transformer tank rupture and subsequent fire damages.

Transformer oil

energy

Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Its functions are to insulate, suppress corona discharge and arcing, and to serve as a coolant.

Transient (oscillation)

energy

A transient event is a short-lived burst of energy in a system caused by a sudden change of state.

Transient response

energy

A transient response is the response of a system to a change from an equilibrium or a steady state.

Transient state

energy

A system is said to be transient or in a transient state when a process variable or variables have been changed and the system has not yet reached a steady state.The time taken for the circuit to change from one steady state to another steady state is called the transient time.

Transitional water

energy

Water depths from 30 to 60 meters.

Translifter

marine

Hydraulically raised and lowered trailer which can slide through the center of a wheel-lesscassette to load and discharge it from the vessel

Transmission efficiency

marine

The ratio of delivered power to shaft power.

Transmission network

energy

The interconnecting lines between power plants and substations that carry high voltage electricity.

Transmission service request

energy

In the electric power industry, a transmission service request is an application requesting a transmission-owning utility to allocate physical capacity in the form of transmission service rights for the transmission of electric power.
