[0002] In electrical secondary work, newly laid cables or cables that have been in operation for a long time must be tested for insulation to ground. A common practice is to suspend both sides of the cable in the air and test it with an ohmmeter or an electronic insulation meter. Since the insulation test uses a high voltage, there is residual pressure in the cable after the test is completed, and grounding is required to discharge it, otherwise it will cause electric shock to the staff who touch the cable. At present, there are certain problems with the method of directly grounding the cable for discharge. First, people are prone to electric shock if they accidentally touch the cable core. Second, some cables are limited in length and cannot be directly grounded.
