Tetsurou TAKAHASHI, Hiroki NAGASAWA
It is important for maintenance of contact line on electric railways to measure the residual hight of contact wire. For the purpose of it, an system using Na lamp and line sensor camera have been studied. Field tests on an experimental device were carried out successfully. Using the results of field tests, a new instrument was manufactured in order to install on the roof of an electric car.
