Abstract

DISPOSITIVO ELECTRONICO PARA MEDIR CONRRIENTE EN UNA LINEA DE TRANSMISION DE ALTA TENSION Y TRANSMITIR LOS VALORES MEDIDOS MEDIANTE FIBRAS OPTICAS. PARA MEDIR LA CORRIENTE QUE FLUYE POR LA LINEA SECONECTA UN SHUNT (11), QUE TIENE UN TUBO CONDUCTOR INTERIOR, EL CUAL SUMINISTRA SEÑALES DE TENSION PROPORCIONALES A LA CORRIENTE QUE CIRCULA POR EL MISMO. LOS AMPLIFICADORES (21,25) Y LOS CIRCUITOS MUESTREO (23,24), LOS CONVERTIDORES (21,22) Y EL REGISTRO DE DESPLAZAMIETO CONVIERTEN LA SE!AL DE SALIDA DEL SHUNT (11) EN UNA SEÑAL DIGITAL CODIFICADA, QUE ES TRANSMITIDA POR UN DIODO LUMINOSO (29).
