Abstract

PROCEDIMIENTO PARA MEDIR LA CORRIENTE DE LINEAS DE ALTA TENSION Y TRANSMITIR LOS VALORES MEDIDOS A TRAVES DE UNA FIBRA OPTICA. EN PRIMER LUGAR, SE FIJA UN ELEMENTO DE SHUNT QUE TIENE UN NUCLEO CONDUCTOR RESISTIVO Y UNA CAMARA INTERIOR A LA LINEA DE ALTA TENSION Y SE SITUA UN CIRCUITO TRANSMISOR DENTRO DE LA CAMARA. A CONTINUACION SE MIDE LA CORRIENTE QUE PASA A TRAVES DEL NUCLEO CONDUCTOR Y SE CONVIERTE EL VALOR EN UNA SEÑAL DIGITAL. POR ULTIMO SE TRANSMITE DICHA SEÑAL A TRAVES DE UNA LINEA DE FIBRA OPTICA EN FORMA DE IMPULSOS DE LUZ, SE RECIBEN LOS IMPULSOS EN UN PUNTO DETERMINADO Y SE DECODIFICA LA SEÑAL DIGITAL PARA OBTENER UNA SALIDA REPRESENTATIVA DEL VALOR MEDIDO.
