Abstract

Circuito detector del estado de un capacitor, caracterizado porque comprende una resistencia eléctrica, dispuesta en serie con el capacitor, y un elemento de control de un circuito de alarma, óptico o acústico, activable por dicha resistencia, cuya resistencia es de pequeño valor, de modo que su efecto sobre el valor capacitivo del capacitor sea mínimo, al mismo tiempo que sea capaz de producir la activación del elemento de control por efecto de la disminución en el paso de corriente a través de la resistencia, cuando el valor del capacitor baja de ciertos límites.
