Title: The Innovative Contributions of Stefan Breuer
Introduction
Stefan Breuer is a notable inventor based in Pettenbach, Austria. He has made significant contributions to the field of electrical engineering, particularly in the area of arc detection and fault recognition in electrical systems. With a total of 4 patents to his name, Breuer's work has had a meaningful impact on safety and efficiency in electrical applications.
Latest Patents
One of Breuer's latest patents is focused on arc detection. The invention aims to detect an arc in an assembly for transmitting direct voltage. This is achieved through a communication transformer that includes a primary and a secondary winding. The secondary winding connects to a transmitting device designed to impress a communication signal onto it. The primary winding connects to one of the direct voltage lines, allowing the transformed communication signal to be fed into the system. An arc detection unit is connected to the secondary winding to identify the arc signal caused by an arc.
Another significant patent is the AFCI self-test. This invention recognizes faults in arrangements that include a transformer with a primary winding connected in series with a DC voltage line. The secondary winding is magnetically coupled to the primary winding, and an evaluation unit processes the secondary signal. By determining a signal component at a specific frequency and comparing its level to a threshold, the system can detect faults when the signal level falls below the threshold.
