Methods to measure the ground lift voltage are described. From this voltage the ground impedance can be determined. The ground impedance is equal to the DC resistance for low frequencies. However, for high frequencies the ground impedance is determined by the external inductance, and, if this external inductance is very small, by the AC resistance too. The obtained inductance figures are compared with theoretical values. PC board transmission lines are discussed in particular.
