Abstract:

The weakest link in powering high-speed rail locomotives is the carbon strip of a pantograph collector which makes physical contact between the overhead power line and the electrical supply wires of the locomotive. This research effort aims to detect and distinguish the degradation effects of the carbon strip by monitoring the locomotive’s input current line. A pulsed-power carbon strip degradation test stand was designed, built, and tested based on static degradations. Using pulsed power techniques, peak currents attained are on the order of maximum AC/DC currents drawn by the locomotive.
