Title: Innovations of Hans-Eberhard Simmel
Introduction
Hans-Eberhard Simmel is a notable inventor based in Karlsruhe, Germany. He has made significant contributions to the field of electrical engineering, particularly in the development of methods for generating circuit-breaking and tripping signals. With a total of 4 patents to his name, Simmel's work has had a considerable impact on safety mechanisms in electrical systems.
Latest Patents
One of Simmel's latest patents is a method for generating circuit-breaking signals. This method relies on the magnitude and duration of excess current to create a circuit-breaking signal. The process involves sampling a measured quantity derived from the excess current, converting it into digital values, and applying a predetermined function to these values. The addition of these values continues until the sum exceeds a predetermined comparison value. To enhance this method, Simmel introduced an auxiliary quantity that prevents false interruptions of the circuit when the excess current diminishes.
Another significant patent is a method for generating a tripping signal based on the magnitude of an overcurrent. In this method, sampled measurement values are converted into digital values, which are then weighted and summed according to a predetermined function. If the sum exceeds a reference value, a tripping signal is generated. Simmel's innovation allows for the cancellation of the addition process if the overcurrent is decaying, ensuring that the tripping signal is only formed under appropriate conditions.
