Embedded Device Concept for Earth Surface Potentials Measurements of a Grounding System

Large substation grounding system needs to be periodically inspected in order to assure safe and reliable original purpose. Due to complicated measurements including a large amount of measuring points and a complex evaluation of measuring results, final results and conclusions are not immediately obvious. The basic idea is to build an intelligent system in order to get a rapid overview of a grounding system condition with a detailed measurement plan and on-site data analysis feasibility. For this purpose, an embedded device concept for earth surface potentials measurements of a grounding system is proposed. The described device acts as a portable measuring subsystem in conjunction with a personal computer-based integrated program environment or as a stand-alone measuring unit. The presented concept showed excellent properties regarding measurement time saving and measurement costs reduction, by simplifying the project manipulation and by automating the measuring procedures, analysis and documenting.
