The subject of his thesis was "The Transductor, D.C. Pre-Saturated Reactor." His employment began shortly after the completion of his master's degree and a short compulsory period of service in the Swedish military. As was customary for newly graduated engineers, he entered an apprentice program in with ASEA.

Page 58 - The Transductor, Dc Pre-saturated Reactor, with Special Reference to Transductor Control of Rectifiers," Esselte Aktiebolag, Stockholm, Sweden, Appears in 11 books from Saturable reactors have a non-linear voltage-current characteristic so that when the voltage across the reactor rises above a certain threshold, the reactor current increases disproportionately due to core saturation.

As a result, its effective impedance reduces below that without saturation. The paper reviews briefly the transductor-type d.c.

transformers which are at present in use, including the type using two sets of cores and 90° phase displacement between their auxiliary a.c. supplies. It is shown in the paper that a transductor-type d.c. transformer can be constructed without core duplication, but which nevertheless avoids the production of commutation pulses or notches transductor Cited by: 7.

Transductor References Updated 27 February Aggers, C.V. and W.E. Pakala, "Direct-Current Controlled Reactors," The Electric Journal, Febpp. A Saturated Core Reactor can have a single core and only one A.C winding as shown in figure (A) this type of reactor is used since the alternating current in the upper winding producing an A.C voltages in the lower winding (D.C winding) that may be disturbed or damaged the DC control circuit.

The transductor is a fairly recently rediscovered simple electrical device of considerable adaptability and usefulness in a wide range of electric circuit techniques.

The mechanical structure of a transductor is analogous to that of an iron-core transformer, but electrically the device is a d.c.-controlled ferromagnetic-core inductor of variable effective impedance, the impedance being changed.

Nuclear reactor designs are usually categorized by “generation”; that is, Gen-eration I, II, III, III+, and IV. The key attributes characterizing the develop-ment and deployment of nuclear power reactors illuminate transductor essential dif-ferences between the various generations of reactors.

The way forward is tied to clear objectives, leading to the commissioning of experimental fast reactors (CEFR in China in ), the restart of the industrial. Batch reactors are operated with all the material placed in the reactor prior to the start of.

Patterns in C – Part 5: REACTOR By Adam Petersen This final part of the series will step outside the domain of standard C and investigate a pattern for event-driven applications.

The present chapter is aimed to provide a simplified overview of the catalytic reactors used in chemical industry. Each reactor type is described in terms of its key geometric properties, operating characteristics, advantages, and drawbacks among its alternatives and typical areas of use.

Lecture (9) Reactor Sizing Chemical kinetics is the study of chemical reaction rates and reaction mechanisms. The study of chemical reaction engineering (CRE) combines the study of chemical kinetics with the reactors in which the reactions occur.

While describing this device at a lecture in the United States he also mentioned that the same principle could be applied to resistors, making a transistor.

This was the name later applied to the solid-state amplifier. A saturable reactor in electrical engineering is a special form of inductor where the magnetic core can be deliberately saturated by a direct electric current in a control winding. Once saturated, the inductance of the saturable reactor drops dramatically.

This decreases inductive reactance and allows increased flow of the alternating current (AC). AC Line Reactors - AC Load Reactors Controlled Magnetics produces popular three-phase AC line reactors in which three isolated inductors are each wired in series with one of the three line phases.

These reactors serve to filter out current spikes and may also. Neutral earthing reactors limit the line-to-earth fault to specified levels. Specifications should include unbalanced condition, continuous current duration and short-circuit current duration.

Iron-core reactors. Trench offers special reactors incorporating dry type iron cored reactors with air. D thesis was titled, in English, "The Transductor, DC Pre-Saturated Reactor". While describing this device at a lecture in the United States he also mentioned that the same principle could be applied to resistors, making a transistor.

This was the name later applied to the solid-state amplifier. A nuclear reactor in such a stable self sustaining condition is said to be critical and k is equal to unity. Any deviation in the value of k from unity will lead to an increase or decrease in the number of neutrons and hence in the number of fissions.

This in turn will change the rate of heat release in. Reactor for Power Flow Control in Electric Transmission Systems: Modeling and System Impact Study."

Water-cooled, plate-fuel reactors use enriched uranium fuel in plate assemblies (see above Fuel types) and are cooled and moderated with water.

They operate over a wide range of thermal power levels, from a few kilowatts to hundreds of megawatts.
