This paper proposes a new simulation method for contact loss when high voltage bus cables are used in a DC feeding system. To reduce the arcs caused by contact loss, two pantographs are connected by high voltage bus cables which make a closed circuit with a contact wire and pantographs. However, it has not sufficiently been made clear that the increase of this closed circuit inductance as well as pantograph current lessens arc reducing effects. Although the current collecting performance of overhead contact-line-pantograph systems is evaluated by contact loss when high voltage bus cables are used, the detecting accuracy of contact loss measuring methods has not quantitatively been investigated either. The author has developed a simulation method for contact loss having an exponential distribution, and revealed quantitatively the amount of arc reduction and the detecting accuracy of contact loss measuring methods by applying this simulation method.
