The article considers issues of electromagnetic compatibility of traction network with the rail circuits. A mathematic model is elaborated for evaluation of distribution of harmonics of traction current on the length of feeder zone and determination of th... see more

The original automated method of measurement of electrical noise in the return electric-traction network is proposed. It is realized on the base of car-laboratory “Automatics, telemechanics and communication”. The mathematic model of return electric-tract... 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

Abstract. The primary aim of this article is to analyze feelings of belonging and the notion of transnationality among descendants of Portuguese emigrants who have returned to Portugal. The key considerations of the analysis are the multiple interactions ... see more

The article is a continuation of analysis of the electric equivalent AC circuit «traction substation - device of transversal compensation  - electric-traction network  - electric locomotive DS 3» and the influence on a power  transformer in... see more

An indirect method of electric power losses determination in traction network was examined. An example of solving same task with the help of specialized imitation model and results of statistic analysis are adducted. Possible ways of using given results a... see more

The article is a continuation of analysis of mathematical models for AC systems, in which the elements of electric-traction network and switch-on of power transformer in an idling mode are gradually connected. The numerical calculations and analysis of cu... see more

In this article the aspects of model construction for  exploring the electromagnetic processes in the electrictraction DC network are considered.
