Measurements of the frequency-dependent impedance of a thin wire with ground return is performed. We argue that the results from a downscaled experimental setup are useful and relevant for power-line applications. The experimental result is compared with two categories of line models. The first category is a model that uses fixed line parameters and the second category consists of models where the inductance and the resistance are frequency dependent. As expected, the frequency-dependent line parameters must be used in the modeling for consistency with the measurements. The result shows that measurements are important to determine the accuracy and limitations of different simulation models.
