dc.description.abstractWe attempt to apply new method for locating fault point by injecting high-frequency short pulse into overhead distribution line. This method, which is called as TDR (Time Domain Reflectometry) measurement, enables us to detect the fault point easily by measuring propagation time of the pulse reflected due to impedance change at the fault point. In our prior research, we confirmed that TDR measurement method can be applied in overhead power distribution system, and weclarified the propagation characteristics [1].Because the pulse wave is reflected not only from the fault point but also from the branch point of the line, in order to sense reflected wave more precisely, we need to remove reflected waves other than fault point.In this paper, we propose new method which utilizes waveforms measured before and after the distribution failure. Through experiments, we confirmed improvement of new method’s sensing ability and verified the applicability of new method for prognostic failure detection.
