Abstract :
Measurements of impedance made on 5 sizes of rails and on 2 types of bonds are reported in this paper; the investigation covered a range of current per rail of 20 to 900 amp, and frequencies of 1 5 to 60 cycles per second. Results are given in a form convenient for engineering use, and include information for applying corrections For bond impedance and For temperature.
