Problems solved by technology
[0002] In recent years, longitudinal protection has been widely used in line protection of various voltage levels. Since the channel equipment and links contained in the channel are particularly complex, there are more and more channel problems that follow, but the channel detection method still remains In the state 20 years ago, many channel problems often need to be found after the channel is completely interrupted, and cannot be found and resolved when the channel is sub-healthy, causing great safety hazards to the operation of the line

Description
technical field [0001] The invention relates to the application field of detectors, in particular to a special detector for protection channels used in substations and power plants to provide more intuitive data for the detection of longitudinal protection channels in stations. Background technique [0002] In recent years, longitudinal protection has been widely used in line protection of various voltage levels. Since the channel equipment and links contained in the channel are particularly complex, there are more and more channel problems that follow, but the channel detection method still remains In the state 20 years ago, many channel problems often had to be found after the channel was completely interrupted. They could not be found and resolved when the channel was sub-healthy, which caused great safety hazards to the operation of the line. Contents of the invention [0003] In order to solve the above-mentioned problems in the background technology, the object of th...
