Purpose. The work is aimed to study the change in parameters of traction electric motors of trolleybuses during operation and improvement of the technical state control system, using modern diagnostic methods. Methodology. Solution of the scientific ... see more

The traction transformer of the traction drive system of a high-speed train is one of the main equipments for energy conversion. The transformer loss will be increased by load harmonics and pantograph arcs at high speed. It is very important to predict lo... see more

Socio-economic and demographic conditions play an important role to determine pattern and magnitude of electrical and electronic equipment (EEE) consumption in Bangladesh. The urban area is considered the potential hot spot of e-waste generation as consum... see more

In wireless sensor networks, for improving the time synchronization perfromance of online monitoring and application of ZigBee protocol, a scheme is designed. For this objective, first of all, the ZigBee protocol specification is summarized, a profound an... see more

Specific indicators of heat and electric power consumption per unit of food production have object-oriented properties, since they are determined on the basis of methods that are suitable only for a particular enterprise. It is shown that the system appro... 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

A detailed research on the magnetic properties, preparation, and application of two-phase composite magnetic material was conducted in this paper. Firstly, in order to obtain the characteristics of high remanence and low coercivity, a micro field mathemat... see more
