Field and laboratory demonstration of a fiber-optic/RF partial discharges monitoring system for hydrogenerators applications / Rosolem, J. B. in IEEE transactions on energy conversion, Vol. 25, N° 3 (Septembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 3 (Septembre 2010) . - pp. 884 - 890 Titre : Field and laboratory demonstration of a fiber-optic/RF partial discharges monitoring system for hydrogenerators applications Type de document : texte imprimé Auteurs : Rosolem, J. B., Auteur ; Floridia, C., Auteur ; Sanz, J.P. M., Auteur Année de publication : 2011 Article en page(s) : pp. 884 - 890 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Fibre  optic  sensors;  hydroelectric  generators;  hydroelectric  power  stations;  optical  fibres;  partial  discharges;  power  system  measurement Résumé : In this paper, we present the results of a hybrid fiber-optic and RF-sensing technology for monitoring partial discharges on hydrogenerators, which can also be used for several other applications. The main advantages of the proposed system are passivity, flexibility, nonintrusive, inherently dielectric, and human and equipment risk-free. We describe the performance evaluation of the sensing system in laboratory and in field trial installed in a hydroelectric power station located in north of Brazil.
