Abstract
PURPOSE: To enable to search the failed point clearly, independently of the presence of external noise, and to simply search the failed point, by superimposing search signal on the overhead distribution line concerned on failure and moving the receiver along the distribution line.
CONSTITUTION: The search signal is superimposed on the overhead distribution line 2 concerned with failure. On the other hand, the receiver 5 is moved along the distribution line 2 and the variation of the search signal incoming to the receiver 5 is caught and the failed point A is discovered, allowing to sound out the failed point A very easily and cartainly. As the search signal, the signal modulating the carrier signal with the modulated signal is used. On the other hand, at the receiver 5, the signal received with the antenna 20 is given to both the carrier filter and modulation wave filter, and the display section is responded with the signal. Thus, in case of failure search, if external induced noise signal as well as the search signal is incoming to the antenna 20 and the reception signal is increased or decreased greatly, stable display is kept in the process of sound section B moved, and remarkable variation in the display is made when reaching the failed point A to display the failed point A.
