  • Patent number: 10707677
    Abstract: A differential protection method allows monitoring a three-phase transformer. Current measured values are recorded for each phase on all sides of the transformer, a phase-related formation of difference values is carried out using the current measured values from a reference side and amplitude-adjusted and phase-angle-adjusted current measured values from all other sides. An internal error is detected if a difference value exceeds a threshold value. In order to form the amplitude-adjusted and phase-angle-adjusted current measured values, the current measured values recorded for all phases are initially subjected to an amplitude adjustment and then to a phase angle adjustment. In order to allow the phase angle shift to be freely adjusted, a defined matrix equation with a defined matrix coefficient is used for the phase angle adjustment of the current measured values from the particular other side of the transformer. There is also described a differential protection device.

  • Patent number: 10705511
    Abstract: A system for implementing automation functions through abstraction layers includes a control application and an automation equipment abstraction framework executable in a runtime environment. The control application is designed to communicate with automation equipment using one or more automation functions. Each automation function comprises one or more equipment-agnostic instructions. During execution of the control application, the automation equipment abstraction framework receives an equipment-agnostic instructions and an indication of a particular unit of automation equipment. The automation equipment abstraction framework translates the equipment-agnostic instructions into equipment-specific automation instructions executable on the particular unit of automation equipment. These equipment-specific automation instructions may then be sent to the particular unit of automation equipment.

    Abstract: A device for additive manufacturing, in particular powder-bed-based additive manufacturing, having a build-chamber wall, which defines a build chamber and is designed to separate the build chamber from an outside area. The build-chamber wall has a hatch, which is designed for transferring at least partially a component that is to be built up in layers from the build chamber through the hatch into an outside area during an additive manufacturing process, and the component can be built up along at least one transferring direction beyond a dimension of the build chamber. A corresponding method includes the provision of a first portion of the component to be manufactured in layers in the build chamber, and the building up in layers of a second portion, adjoining the first portion, wherein an already built-up sub-portion of the component is transferred in layers from the build chamber through the hatch into the outside area.

  • Publication number: 20200211363
    Abstract: Sensors of a control system transmit detected cyclical actual states of a technical industrial process to a common central unit via a first protected connection of a first open communication network once within a specified time window. The central unit transmits cyclical control signals commensurate with the actual states to multiple actuators via a second protected connection of a second open communication network once within the specified time window. Each sensor supplies the actual state detected by the sensor to the first open communication network within a respective transmitter-side sub-region within the time window. The central unit receives the transmitted actual states within a respective corresponding receiver-side sub-region within the time window. The transmitter-side sub-regions of the sensors are specified such that the receiver-side sub-regions are disjointed from one another.
