    Practical test methods and techniques are presented for measuring the electrical characteristics of grounding systems. Topics addressed include safety considerations; measuring earth resistivity; measuring the power system frequency resistance or impedance of the ground system to remote earth; measuring the transient or surge impedance of the ground system to remote earth; measuring step and touch voltages; verifying the integrity of the grounding system; reviewing common methods for performing ground testing; reviewing instrumentation characteristics and limitations; and reviewing various factors that can distort test measurements.
