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.
