Recent progresses in the technology of the Ni-Zn batteries have a direct influence on the improvement of the performance of hybrid electric vehicles. This paper evaluates the progresses of these batteries in particular for application on hybrid light vehic ...
Recent power quality studies have been focused on the source-identification of voltage disturbances at distribution network busses. This paper describes a method aimed at correlating indirect-lightning events with power systems relay operations, associated ...
The amplitude-enhancement effect of ground resistivity and corona on voltages induced by lightning electromagnetic fields on overhead transmission lines, earlier analyzed by the authors in previous works, is here emphasized. Various examples explaining the ...
Methods aimed at locating the position where a fault is occurred can be seen as part of a complex measurement system oriented at more general power quality purposes. This paper faces the comparison between two methods recently proposed in literature for fa ...

In this paper, we investigate the effect of periodically-grounded shielding wires and surge arresters on the attenuation of lightning-induced voltages. We discuss the adequacy of the commonly made simplification of assuming the shielding wire at ground pot ...

Based on the transmission line approximation, three different equivalent formulations have been proposed for evaluating the interaction between an external electromagnetic field and a transmission line. The difference among these 'coupling' formulations, w ...
