POWER DISTRIBUTION ACCIDENT SEARCHING APPARATUS

摘要

PROBLEM TO BE SOLVED: To reduce in size, weight and cost a power distribution accident searching apparatus by easily and rapidly executing an accident searching work by decreasing in size and weight a voltage applying unit. SOLUTION: The power distribution accident searching apparatus searches a ground point of a ground fault accident occurring at a power distribution line 1. The searching apparatus comprises a transmitter 2 connected to an arbitrary ground point of the line 1 in an accident section separated from a sound section of the line 1 and having a DC power source 6 for applying a DC voltage to the line 1 of the accident section, and a receiver 3 selectively connected to an arbitrary measuring point between the connecting point of the transmitter 2 and the ground point of the ground fault accident or an arbitrary measuring point except two ground points of the connecting point of the transmitter 2 and the ground point of the ground fault accident and having a DC current detector 7 for detecting the DC current flowing to the line 1 by applying the DC voltage by the power source 6. The apparatus can specify the ground point of the ground fault accident according to an amplitude or a direction of the DC current detected by the detector 7.
