Firstly, electrization knowledge related to the research is introduced. After a deep study on various contact loss detection techniques, especially on the electric arcs detection techniques, we draw the conclusion that the untouched detection technique based on phototube sensor can acquire exact contact loss information, and will to be the leading technique for contact loss measurement in future. Secondly, combining with the special railways system in our country, we analyze the cause of the arcs, and the influence on the power supply system and the on board traction drive due to the arcs in detail, and study the arcs' spectrum characteristic. We also analyze detecting principles and put forward with a method - using phototube sensor to detect the contact loss arcs, conceive the configurations and detection flows of the measurement.
