Demand for useful heat it is the essential condition in the qualification of electricity production in high efficiency cogeneration. A solution to provide the demand for useful heat and compensation of load variations over ...

This paper presents a shielding effectiveness evaluation for some metallic threads materials. The tests were performed using a non-standardized method in a dual transversal electromagnetic cell (DTEM). The materials’ ...

This is a study presenting the impact of the long transmission lines on the overvoltage distribution across power transformer windings. The overvoltage propagates along the transmission line until reaches a HV winding, ...

This paper presents a study regarding the conducted electromagnetic emissions of a wireless power system. Due to the fact that in the last few years there have appeared a lot of devices with wireless systems, it must be ...

Electromagnetic shielding is one of the most important concerns of operators from high and very high voltage field, especially those carrying out live work. The electromagnetic field generated by high-voltage overhead power ...

Some aspects concerning the optimal design and sizing of an asynchronous traction motor are described. The motor must be integrated with a static converter in the traction system of a locomotive driving a multiple unit ...

The problem studied in this paper and described in the literature is determining the fundamental frequency of a non-trivial signal in real-time. Using the gradient-descent algorithm, a new optimized method for fundamental ...

In the paper is used the Simpowersystems program which is used for calculating the static mechanical characteristic and operating characteristics within the range of variation of rotor slippage. Also, the program can be ...

This paper emphasizes technical and economic parameters at direct-on-line starting of low power asynchronous motors. There are presented a lot of simulations and there are carried out experimental tests, in order to establish ...

Based on the fact that the three-phase induction machine proves higher performance under six-phase supply, which was demonstrated in Part 1 of the paper, this work investigates the fault-tolerance capability of the six-phase ...
