Abstract

This study includes measurements and analysis of the characteristics of the grounding system in the area of ​​the dam, sluice chamber, pressure pipeline, engine room and switchgear. The following measurements were carried out: Measurement of the resistance of the earthing conductor: Measurement of the potential of the ground points in the appropriate directions as well as measurement of the potential of metal masses: Measurement of the contact voltage in the area of ​​the power plant, administration building, dam and sluice chamber: In addition to the measurements themselves, the study includes an overview of the basic protective characteristics of the grounding systems, with reference to the regulations: principles of measuring the resistance of the spread and step voltages: the procedure for determining the current relevant for determining the potential image of the earthing conductor and analysis of the measurement results.
