The results of determination of power loss level in magnetic conductor of high frequency three-phase traction transformer are presented in the article.

The analysis of power indices of process of compensation of magnetic and mechanical losses in the charts of mutual loading of hauling electric motors with the use of electric power source is resulted.

The less-rare-earth interior permanent-magnet synchronous machines (LRE-IPMSMs), which have the advantages of high power density, high efficiency, and low cost, are promising candidates for electric vehicles (EVs). In this paper, the equivalent magnetic c... see more

Inter-turn short circuit of field windings (ISCFW) may cause the field current of a generator to increase, output reactive power to decrease, and unit vibration to intensify, seriously affecting its safe and stable operation. Full integration of mechanica... see more

Complete and accurate spatial magnetic field description is the premise of effectively assessing the power supply capability of a high-speed railway (HSR). Its evaluation indicators are the current distributions and the integrated impedance of traction ne... see more

It has been proposed to use power losses as an additional energy parameter to complement basic energy indicators in determining the short circuit mode in a traction power grid. Three techniques have been reported to determine the transitional characterist... see more

For an energy-harvesting wireless transmission system, considering that a transmitter which can harvest energy from nature has two kinds of extra energy consumption, circuit consumption and storage losses, the optimization models are set up in this paper ... see more

Based on the controlled parameter speed and acceleration change measurement along with use of a current-limiting reactor, short circuit currents protection efficiency increase system has been proposed. To achieve this goal, a number of auxiliary tasks hav... see more

The conditions of compensation of magnetic and mechanical losses during the test of hauling electric machines according to the Potier’s chart are considered.
