Detecting stray currents in electric railway systems

摘要: In a system and method for detecting stray currents in an electric railway track, at least one magnetic field sensor is provided, which configured to sense values of parameter. The moved along the senses parameter sensing locations track. sensed are processed determine condition track by comparing, portion current path comprising first location second different from location, value with if differs predetermined amount, then marking as portion. mounted on vehicle displacement A voltage applied between rail earth, flow through rail.
