Title: Stefan Gies and Patents for Electrical Fault-Current Protection.
Introduction
Stefan Gies is an inventor based in Wuppertal, Germany. His patent work includes systems designed to detect electrical fault currents and protect devices by disconnecting them from a power supply. He is associated with Siemens Aktiengesellschaft and has 2 patents.
Latest Patents
Gies’s listed patents address fault-current detection and protection-system control.
“Software-Controlled Evaluation of Fault Currents for Protection and Monitoring Systems” describes a system that detects fault currents on a conductive power path. A detector sends a signal to a controller, which evaluates characteristics of the current and identifies its type. The controller sets a corresponding trigger-current value and instructs a switch to isolate the electrical device when the current exceeds that threshold. The patent also describes software for operating the detection system.
“Fault Current and Differential Current Detection System Capable of Preventing Spurious Triggering of a Protection System Due to Transient Interference Pulses” focuses on avoiding unnecessary protection-system activation. Its controller checks whether a detected current reaches a first threshold, waits for a predetermined delay, and then checks it against a second threshold. If the current is identified as a fault or differential current, the controller signals a switch to isolate the device. The patent also covers software executed by the controller.
Career Highlights
Gies’s listed inventions concern electrical safety, current monitoring, and the controlled isolation of devices when potentially hazardous currents are detected. Both patents describe controller-based systems that use measured current characteristics and thresholds to guide protective action.
Collaborations
Gies is associated with Siemens Aktiengesellschaft. His listed coworkers include Reinhard Schmid and Markus Huber.
Conclusion
Stefan Gies’s patent portfolio centers on detecting fault and differential currents while helping electrical protection systems respond reliably and avoid spurious triggering.
