Contact loss ratio is widely used for evaluating current collecting system. One of the ordinary methods to detect the contact loss is observing current loss. This method, however, cannot be adapted to the train which does not have high voltage buses. Another way is measuring the light of arc. But there is some kind of errors by other light around the train. The authors propose the new method to detect the contact loss. The voltage of pantograph measured on the train has a little voltage drop caused by arc. This voltage drop contains frequency component which is not included in the original voltage waveform. The contact loss can be measured by use of notch filter or frequency analysis. The investigations and experiments for detecting contact loss were carried out. The results are shown in this paper.
