Electric arc furnace (EAF) is the most dangerous type of load for power systems. It causes different kinds of distortion due to its frequently variable character. Nowadays there are different types of arc furnaces. This article ...
This paper makes a study of a single-phase synchronous 16-pole generator with axial magnetic field and rare earth magnets. A model of the synchronous generator has first been developed, taking into consideration its geometric ...
Illumination sources have been rapidly shifting in recent years to light-emitting diodes (LED), which are capable of producing more than 10,000 cd/m2 at maximum luminance. This light intensity is far greater than ...
In the paper experimental results for the contact resistance between two cross-pressed cylindrical bars of reinforcing steel bars are presented. The diameters of the investigated samples were from 6 to 10 mm. At a DC measurement ...
Тhe paper presents novel idea for construction of intelligence systems for measurements, data collection and control in MV/LV substations. The technical solution is based on developed microprocessor control systems. The system ...
Ceramic materials based on BaTiO3 have been derived by using a standard ceramic technology. Various quantities of H3BO3 and Bi3O3 have been added in order to lower the ...
The reduction of total losses for transformers is of great importance both from economic and environmental aspects. In the paper two optimization techniques, Global Search and Pattern Search, to minimize the total power losses ...
In the paper is presented an analytical approach for calculation of the electric field induced by an axisymmetric current exciter. The region in which the field is determined may have an arbitrary shape. The approach is based ...
Induction heating is a famous technology and very usually used for cooking appliances because of its high-energy efficiency. A mathematical model is adopted for a flat inductor-detail system in this paper and it is used for ...
