要約(英語): We investigate the method of the branch point estimation using the common earthing conductor, when disconnection occurs at the trunk line and branch line of the distribution line with the branch line. The disconnection detection method using common earthing conductor estimates disconnection point from the time difference of the zero-crossing point of the current flowing at the rising of each common earthing conductor in connected the end point of two adjacent distribution lines. When the branch line of the distribution line is broken, the relationship between the time difference between the zero crossing points and the disconnection distance of the current caused by the wire returning to the feed point of the two common earthing lines is shown, and the cause of the time difference at the zero-crossing point is clarified. In addition, the operating conditions for application to actual equipment will be examined and the results will be shown.
