Catenary Inspection System


The Catenary inspection system adopts contact/non-contact measurement to conduct real-time dynamic inspection for the geometric dimension of the Catenary, dynamic parameters of the pantographic network, and the parameters of power supply. It have made technical breakthroughs in real-time processing and synthesizing algorithms of Catenary geometric images, accurate measurement of angle of steady arm, dynamic contact force measurement of pantographic network, continuous measurement of dynamic lift and elasticity of contact wire, etc.
