    Recently, no-load losses P and noise n of transformer cores have been reduced by replacing the former single-step-lap (SSL) joints by multistep-lap (MSL) joints. On the other hand, the application of MSL in model cores was found not only to decrease P and n, but in some cases they increase. The aim of this paper is the investigation of the difference between SSL and MSL with respect to local magnetic conditions at joint regions and their relevance for global conditions in the core. The results show that the joint is the key region of the transformer core, affecting its dynamical behavior in a distinct way. To minimize the iron losses and the noise of the core, the step lap number N should be chosen carefully to avoid the appearance of "virtual temporary air gaps". View full abstract»

    This paper describes a vectorial formalism useful for studying polyphase systems. For this purpose, mathematical tools such as the concepts of barycenter, linear application and kernel are introduced. This formalism generalizes the space vector theory (SVT). A two-level three-leg voltage-source inverter (23VSI) is studied to demonstrate this property. A graphic representation of the homopolar component is also presented. View full abstract»

    This paper presents an approach for a geometrical solution of an optimal power flow (OPF) problem for a two-bus power system (slack and PV buses). The algebraic equations for the calculation of the Lagrange multipliers and for the minimum losses value are obtained. These equations are used to validate the results obtained using an OPF program.

    A simple expression is derived to obtain the direct axis synchronous reactance (xd) of synchronous machines from operating conditions. This method is suitable for obtaining this parameter where original data are lost and no other information is accessible. View full abstract»

    This paper presents the design and implementation of a computer-based instrument to virtually monitor the quality of voltage, current and power in electric power systems. The proposed instrument is capable of performing online measurement functions, including data acquisition, display, and analysis, as well as data archiving. The analysis of concurrent voltage and current waveforms is performed using the wavelet packet transform (WPT) technique to provide the value of power quality (PQ) indices. In particular, the instrument also enables the display of both the temporal and spectral relationship of the original waveforms. Results of actual data are reported to validate the performance of the developed instrument. View full abstract»
