Abstract: Systems, methods, and circuits are disclosed for detecting continuity of a fuse or other current protection device in a circuit. For example, a signal is generated and coupled onto a closed circuit in which the continuity of the fuse closes the circuit. The signal is then coupled from the closed circuit to a signal detector, which detects the presence of the signal and provides an output indicative of the presence of the signal. If the fuse blows, the circuit is opened, prohibiting the signal from being coupled to the signal detector, in which case the signal detector provides an output indicative of the absence of the signal. This example, however, are not exhaustive.

Abstract: The invention relates to a circuit for displaying a fuse failure for a fuse (1) trip status monitoring system. A lighting diode (2) is provided in order to display the trip status of the fuse (1), said lighting diode being arranged in a current path parallel to the circuit (1). When the fuse (1) is not tripped, the parallel current path has such a high resistance compared to the resistance across the fuse (1) that the current across said current path is not sufficient to actuate the lighting diode (2), and when the fuse (1) is tripped, the parallel current path has such a low resistance compared to the resistance across the fuse (1) that the current across said current path is sufficient to actuate the lighting diode (2). Furthermore, a current-limiting device for limiting the current across the lighting diode (2) and a voltage-limiting device for limiting the voltage across the tripped fuse (1) are provided. It is essential to the invention that a field-effect transistor (3) and a resistor (4) are provided in series in order to achieve the high resistance of the parallel current path when the fuse (1) is not tripped, and the same resistor (4) is provided for arranging the current-limiting device in the parallel current path when the fuse (1) is tripped in order to form a control voltage for the field-effect transistor (3) in the parallel current path with the lighting diode (2), the blocked state of the field-effect transistor (3) depending on said control voltage. Thus, a universal and inexpensive circuit is provided for monitoring fuses, said circuit being suitable for direct current operations as well as for alternating current operations.

Abstract: Um bei Niederspannungsschaltgeräten mit möglichst geringem Aufwand, d.h. möglichst wenig Meßstellen und Verkabelung die Betriebsspannung möglichst umfassend und genau zu erfassen und auszuwerten, wird ein Überwachungssystem vorgeschlagen mit vor und nach Schutzorganen, z.B. Sicherungen (16), von zu überwachenden Phasen (R1-R2, S1-S2, T1-T2) vorgesehenen Meßstellen (17, 18, 19), mit einer Meß- und Auswerteeinheit, die mit den Meßstellen verbunden ist, und mit einer mit der Meß- und Auswerteinheit (2) verbundenen Steuereinheit, an der Informationen über die Netzart und/oder eine Auswahl von zu überwachenden Phasen (R1-R2, S1-S2, T1-T2) eingestellt werden können.
Dadurch, daß vor und nach jedem Schutzorgan einer zu überwachenden Phase eine Meßstelle vorgesehen ist, kann auf einfache Weise sowohl die Phasenspannung ihrer Höhe und ihrem Verlauf nach als auch die über dem Schutzorgan anliegende Differenzspannung erfaßt werden, wobei diese Art der Spannungserfassung unabhängig von der Einspeiserichtung ist.
