Abstract

SE DESCRIBE UN PROCEDIMIENTO Y UNA DISPOSICION DE CONEXION PARA LA INSTALACION INTERMITENTE DE UNA TENSION CONTINUA O ALTERNA EN UN ELECTRODO (1) CONTACTANDO CON UN MATERIA ELECTRODO (1) PARA PURIFICACION MEDIANTE UNOS CONECTORES (2). EL PROCEDIMIENTO ES APROPIADO PARA APLICARLO EN TECNICAS DE MEDIDA DE CIRCULACION MAGNETO INDUCTIVAS. EL OBJETIVO ES EL APANTALLADO DEL ELECTRODO (1) FRENTE A LAS CAPACIDADES PARASITAS EXISTENTES EN EL ELEMENTO DE CONEXION (2) ASI COMO DE LOS FALLOS DE TENSION MANIFESTADOS FRENTE AL ELECTRODO (1). ESTE OBJETIVO SE LOGRA YA QUE EN EL LAPSO DE TIEMPO EN EL QUE NO EXISTE TENSION (U) NO SE COORDINA EL ELECTRODO (1) CON LOS ELEMENTOS CONECTORES (2) Y QUE EL POTENCIAL ELECTRICA DEL ELECTRODO (1) SE ACOPLA A LA PIEZA DE CONEXION DE LOS ELEMENTOS CONECTORES (2). COMO ELEMENTO DE ACOPLAMIENTO SE UTILIZAC UN TRANSDUCTOR (4A, 4B) DE IMPEDANCIA.
