Abstract: The invention relates to a power semiconductor device comprising a pin element which passes through a housing opening, comprising a support device, further comprising an elastic sealing device which is arranged on the support device, comprising a pressure device which is arranged on the sealing device, and comprising an electrically conductive sleeve. A first pressure element of the pressure device presses a first sealing element of the sealing device against a first support element of the support device in the axial direction of the pin element causes deformation of the first sealing element so that the first sealing element presses against the housing opening wall and against the sleeve in a perpendicular direction in relation to the axial direction of the pin element.

Abstract: The apparatus serves for inhomogeneous cooling of a flat object with a first main face and a second main face opposite the first main face. The flat object is cooled by a cooling device from the direction of the first main face. On the second main face, a heating device locally acts upon a first partial face in such a way that the flat object is subjected to heat at said first partial face relative to a second partial face adjoining said first partial face in such a way that said first partial face is cooled more slowly in comparison with the second partial face and, during the cooling process, the second main face of the flat object therefore has an inhomogeneous temperature distribution at least in a partial time period of the cooling.

Abstract: A method and a device for detecting and correcting a saturated current profile of a current transformer in a particularly simple and reliable way, initially uses a number of logic inquiries derived from sampled values of the present current signal profile to detect a start of saturation on the basis of a pattern recognition. An end of saturation is subsequently determined, likewise with the aid of a number of logic inquiries. A saturation signal is then formed from a combination of the logic inquiries. In the case of the detection of saturation, the current sampled values are discarded, and an image of the unsaturated current signal profile is reconstructed from a number of sampled values determined ahead of the time of detection of saturation.
