Abstract

La presente invencion se refiere a un dispositivo para detectar las cargas eléctricas en un objeto de prueba (1) con por lo menos dos conductores de conexion eléctricos (1a, 1b, 1c, 1d) que comprende un equipo transductor y un equipo de evaulacion (PA, ABU, LU). El equipo transductor por lo menos comprende un transductor (6a, 6b, 6c, 6d) para la deteccion sensible a la direccion de los pulsos de corriente a través de los conductores de conexion detectando un campo magnético, generado por los pulsos de corriente, y la polaridad de los mismos, el transductor presenta una señal de transductor (v1", v2", v3", v4", v11", v21") al equipo de evaluacion en dependencia de los pulsos de corriente y de su direccion, y el equipo de evaluacion genera, en dependencia de las señales del transductor recibidas una señal indicadora (IND), que indica una descarga eléctrica en el objeto de prueba.
