Title
(EN) DEVICE AND METHOD FOR DETECTING A STREET LAMP FAULT
(FR) DISPOSITIF ET PROCÉDÉ POUR DÉTECTER UNE DÉFAILLANCE DE RÉVERBÈRE
Abstract
(EN)
A device for detecting a fault of at least one street lamp of a plurality of street lamps which are connectable in common to an AC power supply is proposed. The proposed device allows detecting whether a fault has occurred based on obtaining measures representative of the total active and reactive power supplied by the AC power supply to the plurality of street lamps, and detecting variations in these measures. Optionally, also the type of fault can be determined based on detected variations in the power measures.
(FR)
L'invention concerne un dispositif permettant de détecter une défaillance d'au moins un réverbère parmi une pluralité de réverbères qui peuvent être reliés en commun à une alimentation alternative. Le dispositif proposé permet la détection de ce qu'une défaillance s'est produite sur la base de l'obtention de mesures représentatives de la puissance active et réactive totales fournies par l'alimentation alternative à la pluralité de réverbères, et il permet la détection de variations dans ces mesures. En option, le type de défaillance peut également être déterminé sur la base des variations détectées dans les mesures des puissances.
