Abnormal Detection Line Method to Estimate Disconnection Points in Power Distribution Lines

Natural phenomena such as gale, rain, and lightning cause disconnections, which can disrupt power distribution. Therefore, a method that estimate the disconnection point (DP) in distribution lines is needed to ensure public safety stable supply. A simple DP detection using common earthing conductor applied both residential industrial areas with only two interconnection points at ends. However, this cannot be used rural have without points. we propose novel estimation for use areas. To end, an abnormal line was installed along long branch ammeters placed its starting end realized by calculating time difference between zero-crossing of current flowing ammeters. The effectiveness proposed validated simulating lines. Thus, improve performance
