Abstract: The invention relates to a bipolar non-punch-through power semiconductor device and a corresponding manufacturing method. The device comprises a semiconductor wafer and a first electrode formed on a first main side of the wafer and a second electrode formed on a second main side of the wafer opposite the first main side. The wafer comprises a pair of layers of different conductivity types, such as a drift layer of a first conductivity type, and a first layer of a second conductivity type arranged on the drift layer towards the first main side and contacting the first electrode.The wafer comprises an inner region wand an outer region surrounding the inner region. The drift layer has a thickness in the inner region greater or equal than a thickness in the outer region. A thickness of the first layer increases in a transition region between the inner region and the outer region from a thickness in the inner region to a maximum thickness in the outer region. The thickness of the first layer increases linearly over the transition region with a width of the transition region greater than 5 times a thickness of the first section of the first layer.

Abstract: Exemplary embodiments relate to a medium voltage switchgear with interlocking device associated with an actuator drive, which operates a switching element via a mechanical coupling element. The switching drive is movable in two end positions until which the interlocking is active between a freely selectable middle position and a specified end position. In order to keep the interlocking active over a certain range of the actuator travel, the mechanical coupling element includes a force flux element that is rotatable during operation of the drive from OFF to ON. In this way, the region where the interlocking shifts from unlocked to locked can freely be chosen by the shape of the force flux element.

Abstract: A system and method are disclosed for automated handling of at least one working step of a workflow in an automation and/or electrical engineering project via a data input interface, a processing unit and a data output interface connected to the processing unit for transmitting any data read in by the data input interface or generated by the processing unit to at least one of a data repository, another processing unit and/or a display unit. The data input interface can read in input values belonging to the at least one working step of the workflow, and an input uncertainty including a range of input values. The processing unit can generate an output value of the working step from the input value, and calculate an output uncertainty characterizing a range of the output value, by taking into account a parameter and/or a technical condition of the working step.

Abstract: The invention supports and promotes testing of Substation Automation (SA) functions involving intermediary Logical Nodes (LN) in SA systems of operating substations, specifically with minimized impact on the substation and/or the SA system and without having to completely deactivate or isolate entire parts of the substation. A test is set up by defining at least one input LN where the test scenario input signals will be applied, and by determining output LNs where expected output values shall be observed. Based on the data flow between LNs as defined in the System Configuration Description (SCD) file a test preparing tool automatically determines all intermediary LNs logically arranged between these input and output LNs. The intermediary LNs and the IEDs that are affected by the function test are identified and subsequently marked for “test” or “simulation” mode.

Abstract: Among other things, one or more techniques and/or systems are provided for assessing power system equipment of a power system. Historical sensor data and/or historical field test data collected from the power system equipment may be utilized to develop a health profile of the power system equipment. The health profile is indicative of a predicted health (e.g., or probability of failure) of the power system equipment. In one embodiment, the health profile further comprises a health index score which evaluates that health of the power system equipment in terms of the importance of the power system equipment to the power system. Using the health profiles developed for a plurality of power system equipment, a maintenance strategy for at least a portion of the power system may be developed.
