Abstract
For preventing accident occurring at the contact area between overhead catenary system and pantograph, overhead catenary system must be carefully maintained, resulting in requiring heavy maintenance cost. The present on-board monitoring system for overhead contact lines mainly keeps watch on dynamic states of contact wire. However, its static states are extremely required for the efficient maintenance work of the overhead contact line. Therefore, the authors have been developing a method which estimates static height of contact wire by contact force and pantograph height. This paper describes the new method in detail and shows the verification results of on-track test.
