Abstract

Used for automatic acquisition of the electrical behavious of a capacitor element in an a. c. circuit as well as for detecting the presence of reactive (wattless) energy originating from an induction element during marked variation or change of the associated capacitor element, proposed circuit gives automatic detection of faulty capacitors and indicates the correct time-point for exchange or repair. The circuit comprises an electrical resistance (4) connected in series with the capacitor (2) and a drive (control) element for an optical or acoustic alarm (5) circuit that is triggered by the resistance. The resistance value is made small so as to keep its influence on the capacitance value to the minimum, and yet be able to actuate the drive (control) element by reducing the current flow through the resistance (4) when the capacitance value falls below a certain threshold value.
