Abstract: A protection arrangement for inaccessibly located power distribution equipment includes a first enclosure with power equipment and sensors, a second enclosure adjacent the first enclosure and including a signal handling device, at least one sealed electrical conductor passage between the first and second enclosures, each comprising at least one penetrator through the walls of the first and second enclosures. The signal handling device in the second enclosure is connected to the sensors in the first enclosure via electrical conductors passing through said sealed electrical conductor passages and to an external protection device via a communication link. The signal handling device receives electrical sensor signals from the sensors and shapes them for submission to the external protection device.

Abstract: A distributed controller module for controlling a power electronics building block of a power electronics converter includes a plurality of gate drivers for controlling power electronics switches of the power electronics building block, a first fiber optics communication interface for communication with a central controller module, a second fiber optics communication interface for communication with a second distributed controller module for controlling a second power electronics building block of the power electronics converter, and a processor unit for controlling the gate drivers and transmitting and receiving data via the first fiber optics communication interface and the second fiber optics communication interface.

Abstract: In a plasterboard panel a first plasterboard sheet has an opening delimited by a first outer zone of the first sheet; a second plasterboard sheet forms a door which can be connected to the opening in the first sheet, the second plasterboard sheet comprising a second outer zone delimiting the door. The panel also comprises holding means for stably connecting the door to the opening. The first outer zone is tapered transversally to the plane in which the panel lies and narrows from a first flat surface of the first sheet to a second flat surface of the first sheet opposite the first flat surface. The second outer zone is tapered transversally to the plane in which the panel lies and narrows from a first flat surface of the second sheet to a second flat surface of the second sheet opposite the first flat surface.
