MEASUREMENT OF CONTACT LOSS BY DETECTING SPARK

The contact loss between contact wire and pantograph causes many troubles. Thus, to evaluate the current collecting performance, it is very improtant to know the degree of contact loss. In the past, constact loss could be measured on a specially designed inspection car. Therefore, we have developed a contact loss measuring instrument by detecting spark. In this instrument, dector is set at the window or on the top of the roof of the vehicle. Then, arc light is detected through lens systems, and is converted into electric signal. This signal is used to measure the contact loss. By development of this instrument, measurement of contact loss has been made possible on ordinary car.
