Ground impedance measurement in medium voltage substations, designed to operate in a predominantly cable network, is a complex research task. Namely, the inability to consider all the factors that can affect the measured value, in a situation where o

The first step in planning and designing of the proper grounding system, is the earth resistivity measurement. Measurements are carried out before the construction of the power facility. However, it is not an uncommon situation that during constructi

Geomagnetically induced currents (GICs) can cause a range of adverse consequences related to the normal functioning of a power system, e.g. the saturation of power transformers, unusual flows of active and reactive power, voltage fluctuations, the ap

SUMMARY A new practical approach to the shifted frequency method for grounding impedance measurements of high-voltage substation is presented in this paper. The results obtained by the proposed method are compared with the corresponding results obtai

This paper presents the study of a measurement technique for touch and step voltages. In essence, we elaborate an approach which is very similar to the measurement of the grounding system impedance. In addition, the main focus is on the measurements
