Abstract

Nueva protección eléctrica con tiempo de retardo, dependiente de una magnitud regulada, destinada a la protección de líneas y dispositivos eléctricos frente a la aparición de una perturbación que puede consistir en una sobreintensidad, una tensión mínima, etc., caracterizada porque la citada protección comportará un convertidor analógico digital destinado a realizar la toma de la medida de la señal de la magnitud regulada a vigilar, y transformarla en información digital para su posterior procesado, y un microprocesador que procesa la información digitalmente de acuerdo con las curvas características de temporización, que relacionan el tiempo de retardo de actuación con respecto a la citada magnitud regulada, y verifica la comparación digital entre los valores prescritos y los valores de la señal que recibe del convertidor, ordenando la actuación si se ha producido una perturbación en la magnitud regulada y ha transcurrido el tiempo de retardo correspondiente a la cuantía de la perturbación.
