Title (EN) DETECTOR FOR HIGH INTENSITY ELECTRICAL CURRENTS
(FR) DETECTEUR DE COURANTS ELECTRIQUES HAUTE INTENSITE
Abstract:
(EN) The invention discloses a detection- and recording system for high intensity electric currents such as lightning currents in a lightning conductor in a wind turbine. The system comprises a detector (6) containing a power supply (7), a measuring circuit (8), and a converter means (9) and furthermore a recording means (11) non-galvanically coupled to said converter means (9) and a measuring coil (5) to be inductively coupled to an electric conductor (2) carrying the high intensity electric current. The power supply (7) receives its electrical energy directly from the lightning current via the power coil (4) which makes the system non-sensitive to mains supply drop-outs.
(FR) L'invention concerne un système de détection et d'enregistrement adapté pour des courants électriques haute intensité, tels que les courants de foudre dans un paratonnerre logé dans un aérogénérateur. Le système est équipé d'un détecteur (6) contenant une alimentation (7), un circuit de mesure (8), un organe de conversion (9), un organe de lecture (11) couplé de manière non galvanique à l'organe de conversion (9) et une bobine de mesure (5) à coupler par induction à un conducteur électrique (2) acheminant le courant électrique haute intensité. L'alimentation (7) reçoit son énergie électrique directement du courant de foudre via la bobine de puissance (4) qui rend le système insensible aux mises au repos de l'alimentation secteur.
