Title: Wolfgang Röhl: Innovator in Low-Voltage Power Switch Technology

Introduction

Wolfgang Röhl is a notable inventor based in Berlin, Germany. He has made significant contributions to the field of electrical engineering, particularly in low-voltage power switch technology. With a total of 2 patents, his work has had a considerable impact on the industry.

Latest Patents

Röhl's latest patents include a three- or four-pole low-voltage power switch that utilizes Rogowski coils as current sensors. This innovative switch is designed to detect ground faults by producing the current vectorial sum in the conductors of a monitored network. The output signals from the Rogowski coils are processed through resistances to an integration capacitor, which then provides an input signal to a measuring amplifier. This amplifier represents the current sum of the monitored network, and its output is further processed by a microprocessor in an excess-current trip.

Another significant patent is for an electric power switch that features an electronic memory unit for parameters and conversion factors. This electrical power breaker includes an electronic protective device and a memory that is physically separated from the protective device. This design enhances data security by connecting the memory to the protective device via a data bus, allowing for the transmission of control signals to manage write protection.
