Magnetic materials are widespread in many fields of the electronics and electrical engineering. The most of them take place in the constructions of transformers, coil cores, electromagnets, measurement sensors etc. Thus, their ...
The compensation of the reactive loads is fundamental for improving the quality of the industrial electrical supply and decreasing the losses of active power in the distribution grids. Regarding energy efficiency, capacitor ...
The block-diagram of equipment for measuring the velocity of detonation in non-electrical waveguides for blasting is developed. Calibrated time intervals between two pulses corresponding to the specified distance between the ...
This paper examines problems of calculation of heating units for ferromagnetic steel in weak electromagnetic fields. Such installations are low-temperature induction heating installations. In these plants, the electromagnetic ...
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 ...
