Used for handover test of power cables, to check for potential risks during cable transportation or installation, and to ensure the safety and reliability of line operation. Used for pre-test of power cables: to confirm the quality of cable terminals and intermediate joints after maintenance and installation. Used for status diagnosis of running cables, to estimate the status of running cables by measuring partial discharge and dielectric loss of power cables, and to determine the insulation condition of cables after long-term operation, so as to scientifically arrange maintenance and improve the operation efficiency and reliability of cables. Effectively detect various local defects of cables and accurately locate them.
