Title: Locating method for power transmission line accident point
Inventor: KUROIWA YOSHIO
IPC: G01R31/08
Filed: 1987-12-16
Abstract: PURPOSE:To locate an accident point on a branch power transmission line with high accuracy by providing surge sensors, power transmission lines, the branch power transmission line, etc. CONSTITUTION:This method is provided with the power transmission lines 3 and 4, surge sensors 1 and 1 coupled with the power transmission lines 3 and 4 at both end parts of a locating section, and the branch power transmission line 5 which is branched and connected at a 0 point. Then when a surge current is observed over a wide range, a clock pulse oscillator is installed at an A terminal and consequently, the time bases of cathode-ray tube oscillographs placed at, for example, the A terminal and B terminal are swept simultaneously to observe source current waveforms propagated to the A and B terminals respectively. Then, the distance to the accident point is found by measuring the delay time between a line wave and a ground wave contained in the same surge current and compared with the line length of the power transmission lines 3 and 4 to accurately locate the accident point.
