Abstract: A measuring method and a device that permit a better evaluation of bearing currents are disclosed. The method uses non-contact measurement of a bearing voltage. A non-contact voltage measurement is performed by means of a series circuit of capacitors. The bearing voltage can be detected especially well in this manner even in the high frequency range.

Abstract: In a system for ascertaining a bearing state and in a method for ascertaining a bearing state of a bearing of an electric machine, measurement value (21) is ascertained by means of a sensor unit (20). The measurement value is transmitted to a simulation unit (22), wherein a result value (23) is ascertained by means of the simulation unit (22), wherein the result value is in particular a bearing-current value or a value that is dependent on the bearing current. The result value (23) can be transmitted to a further unit (24).

Abstract: The grounding quality of an electric machine should be better monitored. Therefore, an electric machine is proposed, comprising a stator (1), a rotor (2), a shaft (3), to which the rotor (2) is fastened, and a grounding device (5) for grounding the shaft. The electric machine also has a measuring device (6) for measuring a ground current of the grounding device (5) and for providing a corresponding measured value. The electric machine also has a monitoring device (7) for monitoring the grounding function of the grounding device (5) on the basis of the measured value. In this way, the state of a grounding brush in regard to soiling and wear, for example, can be continuously monitored.

Abstract: The invention relates to a method for identifying dirt and/or dew on components of a voltage intermediate circuit converter. According to the invention, the temporal curve of a partial discharge pulsed current is detected at least during a precharging process of an intermediate circuit capacitor of the voltage intermediate circuit converter comprising at least one capacitor, wherein a frequency spectrum is calculated from said current pulse, and wherein depending of the result, a dirt warning and/or a dew warning is activated. Thus, the degree of dirt and/or dew of said voltage intermediate circuit converter can be determined at least during a charging process of an intermediate circuit capacitor of a voltage intermediate circuit converter, thereby preventing a breakdown including the consequences thereof.

Abstract: A strand-like material is formed of CNT yarns that are embedded in a metal matrix. The embedding in a common matrix has the advantage in that the material composite exhibits an improved electrical conductivity. This lies in the ability for electrons to switch from the CNT to the matrix and back again. The strand-like material composite is therefore suitable for use as an electrical conductor. Further proposed is a method for producing the strand-like material composite.
