<P>PROBLEM TO BE SOLVED: To solve the problem that a device for specifying a disconnection position of a distribution line by arranging a voltage/current measuring device on the distribution line and analyzing values obtained at each measured point conventionally determines which section of sections divided with the voltage/current measuring device generates disconnection alone, determination of the disconnection position in the section must be inspected by persons and many times are needed. <P>SOLUTION: A disconnection detecting system of the distribution line arranges the voltage/current measuring devices 1-9 on the distribution line 1, finds a difference between a positive phase voltage and reverse phase voltage obtained at each measured point as a function of a distance on the distributed line, and is provided with a disconnection point calculating device 211 for finding the distance in which the value of the difference is similar. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
