Title: Walter Rueegg: Innovator in Electrical Measurement Technologies

Introduction

Walter Rueegg is a notable inventor based in Endingen, Switzerland. He has made significant contributions to the field of electrical measurement technologies, holding 2 patents that showcase his innovative approach to solving complex problems in electrical engineering.

Latest Patents

One of Rueegg's latest patents is a "Method for measuring the resistance and the inductance of a line." This method allows for the determination of a line's impedance by measuring the voltage applied across the line and the time derivative of the current flowing through it. The unique aspect of this method is that the measured values of the differentiated current are directly substituted into an equation system, eliminating the need for integration. This results in a more efficient way to estimate the values of inductance and resistance.

Another significant patent is the "Method for protection of an electrical power line." In this invention, current and voltage values are measured to protect an electrical power line. An adaptive estimator analyzes these values within a measurement window and converts them to impedance values. If the impedance values reach unacceptable levels, the line is switched off. Additionally, a warning signal is generated if powerful radio-frequency signals are detected, allowing for a quicker response to potential issues.
