Program Support for Earth Surface Potentials Measuring System

Substation grounding systems need to be inspected periodically to test and verify their original protective functionality and characteristics. The most important parameters are the values of touch and step voltages under fault conditions as they directly affect the on-site personnel safety. Grounding system verification is a multi-stage process, which has to be planned in details prior to actual measurements. That implies a need for an elaborated measuring methodology as well as for custom designed measuring system. Prototype of such a system has been developed and tested in the field. This paper focuses on the description of program support as a framework and foundation of a complex measuring system. Application structure, which is tightly bound to measuring methodology concepts, is presented through the typical example of system usage. Additional issues and references to accompanying measuring instrumentation are also presented.
