[0002] The transmission line maintenance device is a cable testing device used to measure the fault location of the transmission line. It can help engineers find the fault point quickly and accurately and improve maintenance efficiency. Before using the transmission line maintenance device, some preparations need to be made. First, the type and location of the transmission line fault need to be confirmed, which can be achieved by observing the appearance of the cable and detecting the electrical parameters of the cable. Secondly, instruments and related tools, such as detection heads and test lines, need to be prepared. Finally, the safety and stability of the test environment need to be ensured to avoid accidents during the test. The faulty end of the transmission line is connected to the detection head of the maintenance device. The detection head needs to be used for detection during the connection to ensure that the connection is stable and reliable.
