The D.C. HiPot adapter is an encapsulated high voltage rectifier for use on the phase tell meters 6702/6706. When used in conjunction with the phase tell it will enable the operator to perform the following tests on systems up to & including 35kV phase to phase: 1. Test sections of underground cable to determine the integrity of insulation, i.e, failed cables. 2. Determine if all grounds have been removed after completion of working on a de-energized underground system. The HiPot adapter housing is fiberglass, 13 in length. A bell shaped female end allows it to be coupled to the end of the phase tell after the conductor hook is removed. The appropriate URD bushing adapter can then be installed on the other end of the HiPot adapter .
