Aiming at the sudden short circuit of three-phase power transformer, some structures of the transformer are reasonably simplified to establish a three-dimensional finite element field-circuit coupling model of the transformer, and the dynamic response of the transformer under three-phase symmetrical short circuit is analyzed by Maxwell transient electromagnetic field simulation. The short-circuit current of the transformer reaches its peak value at 0.0092s at the beginning of the simulation, that is, the inpact current is 14645.8 A, and the distribution of the axial and radial leakage magnetic fields is obtained. Based on this, the electromagnetic force of the winding during short-circuit is calculated.

“…The higher the value of this parameter, the greater the loss and heating of the conductive parts [7][8][9]. This reduces the life of the circuit breakers and their performance [10]. In this article, microsections are analyzed to assess the effect of coating composition on specific transient resistance.…”

The article is devoted to the analysis of the internal structure and properties of a copper-graphite coating applied to a copper electrode. The article provides a calculation of the transient contact resistance of electrodes with a coating obtained using plasma spraying technology. Copper-graphite powder with high arc resistance was used as a spraying substance. Coated electrodes were tested for erosion resistance by an arc at currents of several kiloamperes. The aim of the work is to determine the effect of the composition and internal structure of the coating on the transient processes in the contact gap.

The article deals with the most dynamically developing branch of power electronics related to solving tasks of voltage regulation in DC-to-DC converters. Linear regulation of the output voltage is carried out using pulse-width modulation. A linear regulatory characteristic is obtained over the entire control range from zero to maximum values. The formula of the output voltage regulation characteristic is obtained through a mathematical model of a pulse-width control method with a variable pulse width.
