The contact loss between pantographs of electric rolling stock and contact wire is used to grasp structures of overhead line equipment and current collecting quality. Since the contact loss is mainly evaluated by the contact loss rate and contact loss times, it is necessary to process contact loss signals. Until now, we have used a waveform processing software developed by RTRI, which requires to reproduce data once again after field tests by consuming much time and labor. Therefore, we have developed an automatic processing system for contact loss signals which can the detect contact loss on a real time basis and automatically calculate the contact loss rate, the contact loss duration times, etc. From field tests, we have confirmed that this system has the same performance processing contact loss as the former system has.
