Abstract

Dispositivo electrónico de protección eléctrica en baja tensión, conectable a la red de suministro eléctrico tras un interruptor diferencial por corriente residual presente en gran cantidad de las instalaciones eléctricas de baja tensión, que comprende medios de conexión a dicha red de suministro eléctrico y a un conductor de protección de tierra, caracterizado porque además comprende una unidad de control que mide una tensión de alimentación U{sub,S}, comparando dicha tensión de alimentación U{sub,S} con una tensión umbral U{sub,UMB}, predeterminada, y generando una señal de control cuando dicha tensión de alimentación U{sub,S} sobrepasa dicha tensión umbral U{sub,UMB} durante un tiempo determinado t{sub,MAX} y, una unidad de potencia que, cuando recibe dicha señal de control procedente de dicha unidad de control, genera unas ráfagas de corriente de derivación a tierra que provocan el disparo del diferencial, cualquiera que sea el estado o circunstancia en que se encuentre dicha red de suministro eléctrico.Electronic device for low voltage electrical protection, connectable to the power supply network after a residual current differential switch present in a large number of low voltage electrical installations, comprising means for connecting to said power supply network and to a power conductor earth protection, characterized in that it also comprises a control unit that measures a supply voltage U {sub, S}, comparing said supply voltage U {sub, S} with a threshold voltage U {sub, UMB}, predetermined, and generating a control signal when said supply voltage U {sub, S} exceeds said threshold voltage U {sub, UMB} for a certain time t {sub, MAX} and, a power unit which, when receiving said control signal coming from said control unit, generates bursts of earth bypass current that cause the differential to trip, whatever the state or circumstance in which s and find said power supply network.
