Abstract:
(EN) An overhead-type fault indication positioning terminal, comprising a capacitive sensor disposed in an overhead line electric field. The capacitive sensor is connected to a CPU of the fault indication positioning terminal via a conditioning circuit. Also disclosed is a method for measuring a voltage to ground for the fault indication positioning terminal. The real-time measurement of a voltage to ground voltage of an overhead line is realized, the change in the voltage to ground of the overhead line is captured, and a basis is provided for the determination of a line-to-ground fault.
(FR) La présente invention concerne un terminal de positionnement d’indication de défaut de type aérien, comprenant un capteur capacitif disposé dans un champ électrique de ligne aérienne. Le capteur capacitif est connecté à une unité centrale du terminal de positionnement d’indication de défaut par l’intermédiaire d’un circuit de conditionnement. L’invention concerne en outre un procédé de mesure d’une tension à la terre pour le terminal de positionnement d’indication de défaut. La mesure en temps réel d’une tension à la tension de terre d’une ligne aérienne est conduite, le changement de la tension à la terre de la ligne aérienne est capturé, et une base est fournie pour la détermination d’un défaut de ligne à la terre.
