Abstract :
The definition of ground resistance and ground impedance in the case of alternating currents is discussed. Ground resistance measurements with earth testers are compared with power frequency methods and the errors associated with the location of auxiliary grounds are described. It is emphasized that the ultimate purpose of testing station grounds is to determine touch voltages and potentials arising on communication circuits. Methods are presented to evaluate the adequacy of station grounds, including very large stations.
