This paper presents an analysis of lightning return strokes to tall structures. The interaction of lightning with a tall structure is modeled using the antenna theory. The finite ground conductivity as well as the buried grounding system of the tall struct ...
Photovoltaic (PV) systems are often installed on rooftops or as freestanding systems with no higher surrounding structures. This is why they are often exposed to the influences of lightning which can severely damage these expensive systems. Lightning prote ...
The paper deals with the correlation between lightning and distribution networks faults and/or voltage dips. In particular, the paper presents an application of a method proposed by the authors to correlate lightning events and relays operations based on t ...
In this paper, we compare five engineering return stroke models, extended to include the presence of an elevated strike object, namely the Bruce-Golde (BG) model, the transmission line (TL) model, the traveling current source (TCS) model, and the two modif ...
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 ...
One of the main cause of damages for wind turbine power plants is certainly constituted by lightning. Direct and indirect events can indeed produce damages and malfunctions of electrical and mechanical components. Concerning mechanical components, blades a ...
We present a review of theoretical methods to compute lightning-induced currents and voltages on buried cables. The evaluation of such induced disturbances requires the calculation of the electric field produced by lightning along the cable path. We show t ...
For an improved assessment of the indirect-lightning performances of distribution systems, the real configuration of the system, which means the topology, the presence of protection devices such as surge arresters and shielding wire/neutral groundings, mus ...
In the last twenty years, the widespread use of sensitive electronic devices has increased the interest on transients, in particular those caused by lightning (direct and/or indirect). The paper presents first shortly the developments in modeling the elect ...
The paper deals with the subject of the source-identification of transient voltage disturbances in distribution system buses. In particular, a statistical procedure is proposed for the evaluation of the probability that a lightning flash detected by a Ligh ...
