Abstract
Perfeccionamientos en dispositivos para detectar la desviación de una señal de corriente alterna, caracterizados porque están previstos medios de conexión a los que se alimenta la señal alterna, y porque los medios de conexión están desarrolla para entregar la señal de indicación cuando en el sentido de una parte proporcional máxima o mínima de la señal-DC, la señal abandona completamente durante un tiempo mínimo predeterminado una zona de señal estacionaria predeterminada, o cuando en el sentido de una parte proporcional mínima de la señal-AC, el valor cresta-cresta de la señal alterna sobrepasa durante un tiempo mínimo previsto un valor mínimo previsto, y porque los medios de conexión están desarrollados de manera que éstos se envían a la recepción de una señal de borrado una señal de indicación emitida una vez.
