Abstract
EL TURBOGENERADOR (12), CON UNA POTENCIA DE AL MENOS 1 MVA, ESTA MONTADO EN UN ALOJAMIENTO Y TIENE UN ARROLLAMIENTO EN EL ESTATOR. DENTRO DEL ALOJAMIENTO (1) SE MONTA AL MENOS UN INSTRUMENTO DE MEDIDA DE LA CORRIENTE RESISTENTE A LA ALTA TENSION PARA MEDIR LA CORRIENTE QUE FLUYE EN AL MENOS UNA DE LAS CABEZAS DEL ARROLLAMIENTO DEL ESTATOR. EL CABLE CONDUCTOR DE LA CORRIENTE DEL ARROLLAMIENTO DEL ESTATOR QUE DEBE MEDIRSE SIGUE ESENCIALMENTE EL CAMINO MAS CORTO POR EL INTERIOR DEL ALOJAMIENTO (1). EL INSTRUMENTO MEDIDOR DE LA CORRIENTE CONTIENE AL MENOS UN CONVERTIDOR DE CORRIENTE (3) CON UNA LINEA DE MEDIDA QUE SALE DEL ALOJAMIENTO DEL TURBOGENERADOR (1). POR TANTO, EN EL ALOJAMIENTO (1) ES POSIBLE ACOMODAR UN PUNTO DE ESTRELLA (4) DE LA CORRIENTE QUE DEBE MEDIRSE Y VARIOS CONVERTIDORES DE CORRIENTE (3), EN PARTICULAR PARA UN CIRCUITO DIFERENCIAL DE PROTECCION, LO QUE AHORRA LAS COSTOSAS CONDUCCIONES RESISTENTES A LA ALTA TENSION QUE ATRAVIESAN EL ALOJAMIENTO (1).
