Abstract: A system and a method for renal replacement therapy includes a blood treatment unit connected to a blood circuit and a dialysis fluid circuit, the system further including a control unit configured to control the system according to control instructions during a treatment, so as to determine a system parameter value and an indication of membrane fouling of the membrane, and activate an automatic anti-fouling measure that includes a temporary change of the flow rate in the blood circuit and a temporary decrease of the ultrafiltration rate wherein a timing of the temporary change and a timing of the temporary reduction are synchronized.

Abstract: A high voltage electromagnetic induction device including: a lead-through device-receiving structure having an opening for receiving a lead-through device, a lead-through device extending through the opening, wherein an internal portion is tapering in a direction along the central axis of the lead-through device away from the opening, and an electrical insulation barrier which is arranged in the lead-through device-receiving structure, arranged around and distanced from the internal portion, and which electrical insulation barrier is tapering in the direction, whereby a duct is formed between the internal surface of the electrical insulation barrier and the external surface of the internal portion of the lead-through device, wherein the electrical insulation barrier is tapering relative to the lead-through device such that the distance between the internal surface of the electrical insulation barrier and the external surface of the lead-through device increases in the direction.

Abstract: An insulation system for a winding structure. The insulation system includes an innermost barrier pair arranged to cover a majority of the winding structure in the axial direction of the winding structure inside and outside the barrier structure relative the curvature of winding turns of windings of the winding structure, wherein at least one barrier of the innermost barrier pair defines a first flow path allowing flow of a dielectric fluid mainly in a first axial direction between the winding structure and the at least one barrier when the insulation system is in a assembled state; and a first outer barrier arranged radially inwards or radially outwards relative each barrier of the innermost barrier pair, wherein the first outer barrier defines a second flow path, parallel to the first flow path, allowing flow of a dielectric fluid mainly in a second axial direction opposite the first axial direction.

Abstract: A high voltage arrangement for a high voltage power system has an insulating structure which reduces the creep path. The insulating structure is arranged around the second conductor and has a continuous extension in an axial direction from a first end thereof providing insulation of essentially the entire length of the second conductor to a second end around the bushing portion, which second end extends around the bushing portion at least to a point where an electric potential of an external surface of the bushing portion is at most equal to the average of the potential of the first conductor and the potential of the interfacing plane when the high voltage arrangement is in use.
