    Abstract: A device to locate internal faults in a high-voltage capacitor battery that has a plurality of symmetrically parallel and series-coupled capacitor banks arranged in parallel branches coupled by shunt branches. The phase angles of the shunt currents flowing in the shunt branches relative to the total current flowing in the parallel branches are determined. A fault is located in one of the capacitor banks based upon these determined phase angles.

    Abstract: A monitoring system for detecting earth contact of at least one phase of a polyphase network. Each of the phases in the network is connected by a capacitive-inductive filter to a neutral node which is connected to earth. In one embodiment of the invention, the current flowing from the neutral node to earth is detected by an induction current transformer which provides a signal responsive to said earth current. The output signal of the induction current transformer is conducted through at least one low pass filter for suppressing harmonics, and rectified to produce a direct current voltage signal, the amplitude of which is proportional to the amplitude of the fundamental frequency component of said signal. A fault indicating signal is produced when the direct voltage signal exceeds a predetermined value.

    Abstract: A coating based on diamond-like is formed from a plurality of films of diamond-like carbon formed alternatingly over one another and in this respect a film in which no portion or only a much lower portion of doped fluorine is contained. A film in which fluorine or at least fluorine with a higher portion than the film arranged thereunder or thereabove are formed alternatingly over one another. The coating could be manufactured by using a target of pure carbon. Films are deposited on a surface of a substrate by means of a PVD process, with the portion of fluorine contained in doped form. Films are formed alternately being varied by varying a supplied volume flow of a fluorine/carbon compound or sulfur/fluorine compound as a precursor.
