Abstract
A method and a system for detecting a pantograph-catenary electric arc based on a train power supply system are provided. The method includes: boosting, by a booster transformer, a voltage of alternating current transmitted via an electric network, to generate high voltage electrical energy, where a high voltage and a great current are generated in a gap between a catenary wire and a pantograph in a discharging circuit with the high voltage electrical energy; and collecting an electric arc generated in the gap between the catenary wire and the pantograph in a case of the high voltage and the great current.
