Abstract
PURPOSE: To detect promptly and certainly the mixed contact trouble by arranging the DC converter in the electric system having a large possibility that the mixed contact trouble is generated by the AC and the DC systems, for example, in all phases of the AC system of the electric railway system and by discriminating the secondary current value by the overcurrent relay.
