      Do not look dozens of meters above the ground power overhead wires seem to "years of peace and quiet", but in fact, the transmission line operation process, there are a lot of "irresistible" external hazards, such as lightning strikes, windy and heavy rainfall weather caused by the plastic/tree branches hanging on the wire, Conductors covered with ice, etc., which brings the line lightning fault potential, and a variety of non-lightning faults.

      At the same time, there are also a large number of "preventable" potential defects, such as aging insulators deterioration of insulation capacity, super-high vegetation under the line, insulators high degree of filth, high temperature of the fixture clamps and so on.

      Either way, for the prevention of failure, as well as to assist in the rapid recovery after the failure, "strengthen the field monitoring and early warning", is the first choice for timely detection of hidden problems, pinpointing the point of failure. Traditional inspection and point-by-point investigation methods are time-consuming and labor-intensive, and cannot meet the demands of efficient and stable operation of modern power grids. Therefore, there is an urgent need for a device that can quickly and accurately locate line faults.

      Our transmission line distributed fault diagnostic device, is fast, accurate positioning line fault point "tool", in the event of a fault, laid in the conductor sensors, based on distributed traveling wave measurement technology, it can be detected by detecting, calculating the voltage waveform on the conductor perturbation, to locate the fault point and determine the type of fault, the fault is a lightning strike fault or non-lightning strike fault, fault or non-lightning strike fault, fault or non-lightning strike fault, fault or non-lightning strike fault, fault or non-lightning strike fault, fault or non-lightning strike fault, fault or fault type. Fault is a lightning strike or non-lightning strike fault, lightning strike fault is a bypass or counterstrike for intelligent identification.



      Through the distributed fault diagnostic device, the fault patrol efficiency is significantly improved so that inspectors can find and deal with fault points faster, shorten the fault processing time, and reduce the economic losses caused by fault outages. In addition, the device also reduces the labor cost of cross-area line operation and maintenance to a certain extent, so that the power company can better serve the majority of users.
