The aim of this paper is to present the results of the performance study of medium voltage overhead distribution lines against lightning discharges, in the way to define methodologies to reduce the system failures. The results are obtained within the partn ...
Lightning-induced voltages in power and communication systems are nowadays one of the main causes of power quality and electromagnetic compatibility. In recent years, due to the increasing demand by customers for good quality in the power supply along with ...
The appraisal of the response of distribution networks to the excitation of lightning electro magnetic pulse (LEMP) requires the availability of accurate models of LEMP-illuminated lines. These models should be able to take into account the presence of shi ...
Summary form only given as follows. A model for the calculation of lightning-induced voltages is presented with the aim of assessing the effect of corona when power distribution lines are illuminated by lightning electromagnetic fields. Corona is taken int ...
A model for the calculation of lightning-induced voltages is presented with the aim of assessing the effect of corona when power distribution lines are illuminated by lightning electromagnetic fields. Corona is taken into account by means of dynamic capaci ...
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 ...
Voltage transients are the main causes of complaints from medium-voltage customers. For this reason, utilities and independent authorities are focusing their attention on investigation techniques capable of providing information useful for classifying volt ...
The basic information for designers of lightning protection of MV and LV networks is given in Part I of the present publication. This Part II gives an application of this basic information to the lightning protection of MV networks containing overhead line ...
This paper examines the responses of four different types of shielded conduits to a direct lightning strike. The conduits are buried in the ground and run between two shielded enclosures, one of which is struck by lightning. An induced current flows on the ...
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 ...
