Title: Innovations of Wolfgang Röhl
Introduction
Wolfgang Röhl is a notable inventor based in Berlin, Germany. He has made significant contributions to the field of electrical engineering, particularly in the development of innovative methods and devices for circuit protection. With a total of 4 patents to his name, Röhl's work has had a substantial impact on the industry.
Latest Patents
Röhl's latest patents include a "Method and circuit for measuring a current." This invention describes a method and circuit arrangement that can be utilized in electrical engineering to accurately trigger electronic tripping devices in circuit breakers. The current is measured in terms of magnitude and phase, ensuring that only the fundamental wave of the current is sampled at a low sampling rate. The root mean square is then calculated based on the measured phase angle and amplitude. The exact phase angle is determined using a conventional Phase-Locked Loop (PLL) circuit with a downstream zero switch.
Another significant patent is the "Electronic tripping device for a circuit breaker." This device features circuitry that simulates the response curve of a fuse. It can be controlled by a single setting mechanism that represents the nominal or rated currents of fuses. This innovation enhances the coordination of protection in complex power supply systems that incorporate both circuit breakers and fuses. The new protection system ensures particularly safe operation for users by combining the setting mechanism with a rating plug for the "fuse" mode, allowing for direct setting of the tripping device to a specific current value.
