- Abstract:
- Measurements of the electrical parameters of a traction line were performed over the 0-200 kHz frequency range on a line section purposely prepared at La Spezia (Italy). The electrical parameters are determined by an indirect approach: only the terminal variables (voltages and currents and hence impedance and admittance) may be measured and the per-unit-length electrical parameters are determined using a Multiconductor Transmission Line model of the test track section; the parameters of the model are adjusted so that the calculated terminal variables match the measurement results. There is a general accordance with model previsions, within common variations of the most critical properties, e.g. ground and ballast characteristics and rails permeability; the results are very accurate in the frequency range 50 Hz - 50 kHz.
