MESUREMENT AND DATA PROCESSING ABOUT THE POTENTIAL OF GROUNDING SYSTEMS

Potential distribution on big grounding systems determines the possibility of the appearance of danger voltage. Methods of measurement, processing and the survey of potential distribution so far included many procedures that brought increased inaccuracy and lack of clearness and survey. The aim was determined to improve the processing and survey of measurement data: the potential of measurement points of the grounding systems by help of the adequate software for processing and survey of numerous data. In order to make it possible, the digital voltmeter that is used for potential measurements equipped with measurement data memory unit, and to enable its communication with the computer, through RS-232. The topic of the work is the survey of the development of the memory unit, its communication with computer and the processing of the measurement values of the grounding systems potential in two and three dimensional forms.
