Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
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 statistical assessment of the lightning-performances of distribution lines must take into account the presence of protection devices such as surge arresters and shielding wire/neutral groundings. Indeed, the presence of those devices does modify the in ...
Lightning currents and electromagnetic fields associated with return strokes to elevated strike objects The aim of this thesis is the modeling of lightning return strokes impacting elevated strike objects such as towers. The theoretical and experimental wo ...
The paper is a contribution to the studies of factors that can affect electric (E) and magnetic (H) fields associated with lightning return strokes to tall structure. Herein, the influence of lightning channel inclination upon vertical E-field and azimutha ...
Power line communication (PLC) is a well-known technique for data transmission over low-voltage power lines. The PLC signals have frequency bandwidth of about 1-30 MHz and they may cause electromagnetic interferences with services operating in the same fre ...
In the last twenty years, the widespread use of sensitive electronic devices has increased the interest in transients, in particular those caused by lightning (direct and/or indirect). This paper presents the latest developments in modeling the electromagn ...
Since 1991, a broadband, high-resolution current measurement system has captured the lightning current derivative at the Toronto CN Tower. In this paper, extensive statistics (1992-2001) of CN Tower lightning current waveform parameters (maximum steepness ...
Statistical distributions of lightning current amplitude, time-to-peak and other lightning current parameters used in power system insulation coordination are based on experimental data obtained by means of tall instrumented towers. It is, however, general ...
We present in this paper experimental results obtained at the International Center for Lightning Research and Testing (ICLRT), Camp Blanding, Florida, where currents induced by triggered and natural lightning events were measured at one end of a shielded b ...
We discuss in this paper the influence of the height of an elevated strike object on the magnitude of lightning radiated electric and magnetic fields. For the analysis, the transmission line (TL) return stroke model for the lightning channel is adopted and ...
