A high voltage cable partial discharge tester and method of use thereof

By using a movable arm assembly and a glue-filling locking mechanism to form an elastic sealing layer in a high-voltage cable partial discharge tester, combined with a signal processing unit and a centering screw, the sealing and stability problems of traditional testers in complex environments are solved, achieving high-precision and high-reliability partial discharge detection.
