Abstract
Mejoras en relés de distancia a tierra empleando medición de comparador de fase, para una línea de transmisión, en un sistema de energía de corriente alterna, empleando el circuito de relé, medición de comparador de fase y comprendiendo (a) medios de circuito AND, que producen una señal de salida en el caso de coincidencia de fase de una pluralidad de señales de entrada al mismo, siendo una señal de entrada, una señal polarizante, relacionándose la señal operante con la suma de (1) el producto de la corriente de línea de transmisión y una impedancia de reproducción de la línea de transmisión y (2) voltaje de línea de transmisión y relacionándose la señal polarizante con el voltaje de línea de transmisión y (b) medios de circuito regulador de tiempo, que responden a la señal de salida del medio de circuito de AND para producir una señal de salida de regulador de tiempo, cuando la coincidencia de fase de la pluralidad de señales de entrada al medio de circuito AND es de una duración predeterminada.
