Abstract

La presente invención se refiere a dispositivo de control para la detección electrónica de puntos defectuosos que se presentan en redes de líneas aéreas de corriente alterna, en los que se originan pérdidas de energía para descargas de corona, con una antena para la recepción de las señales de alta frecuencia que se producen en las descargas de corona, un dispositivo amplificador conectado con la antena para amplificar las señales recibidas y un osciloscopio para la indicación visual de señales recibidas, caracterizado porque el dispositivo amplificador está realizado para una amplificación de bandas ancha de las señales recibidas mediante la antena en una banda de frecuencias desde una frecuencia inferior situada por debajo de la frecuencia de corriente alterna de la red de baja frecuencia hasta una frecuencia límite superior de 1 GHz aproximadamente, siendo en el margen de 20 a 200 Mhz la amplificación por lo menos 40 dB y estando reducida la amplificación en el margen entre la frecuenciua límite inferior y 10 KHz aproximadamente, porque la totalidad del espectro de frecuencias de las señales de salida del dispositivo amplificador conducida a un circuito de entrada del osciloscopio para desviaciones verticales y horizontales del elemento de imagen, por lo que en una pantalla del osciloscopio una señal de baja frecuencia producida por la tensión alterna de forma sinusoidal de la red en la línea aérea aparece como una curva cerrada lisa y las señales de alta frecuencia causadas por descargas de corona están representadas por perturbaciones de la curva cerrada, cuya forma de aparición, intensidad y posición en la curva cerrada permiten reconocer el lugar y la clase de un pñunto defectuoso de la línea aérea.
