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.
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 ...
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 ...
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 ...
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 ...
The propagation of the electromagnetic field in fully coated near field optical probes was analyzed. It was proved that these structures allow nonzero modal emission of the electromagnetic field through a 60-nm thick metallic layer. It was also found that ...
Feasibility studies performed in the last years have shown that the low voltage distribution network can be used for data transmission. The main problem is the possible radiation of electromagnetic field representing a the disturbance which can affect radi ...
Voltage sags are one of major concerns in power quality, as they cause serious malfunction of a large number of apparatuses. There are a number of reasons for voltage sags in distribution networks: there is some evidence, however, that in electrical system ...
Feasibility studies performed in the last years have shown that the use of the low voltage distribution network can be used for data transmission. The main problem is the possible radiation of electromagnetic field and the disturbances which can affect rad ...
The CONDOPT (CONDuctor OPTimization) experiment has been recently completed in SULTAN. The current sharing behavior of Nb-3 Sn samples was assessed as a function of the number of cyclic loads experienced during current sweeps in a 10 T background field. We ...
In this paper, an analysis of electric and magnetic fields radiated by lightning first and subsequent return strokes to tall towers is presented. The contributions of the various components of the fields, namely, static, induction, and radiation for the el ...
