Abstract :
The electrical behavior of the sample steel traction rails is analyzed, considering the resistance and internal inductance. Measurements are performed on a sample rail with a circulation of audiofrequency current (with frequency regulated on a wide frequency interval range of 1-100 kHz) superimposed on a dc supply current. The results complete the other measurement results obtained with a 50-Hz bias current; the resistance values are 30%-50% smaller, whereas the internal inductance is almost similar
