Integrated routine inspection device for ground equipment(PD Inspection)

Properties

  • Equipped with the latest AI-based algorithm for underground equipment inspection
  • Can track the PD occurrence location and precisely identify the presence of external interference
  • Can thoroughly inspect the equipment consistently regardless of the user’s experience and skills

SPEC

Technical Data

AI-applied automated analytical algorithm

Properties

  • Automated removal of switch circuit and phase-to-phase high frequency signal delivered.
    – High frequency signal is delivered to another circuit or phase through cable grounding or common bus
  • Analysis of PD Pulse delivered over long distance though cable, automated identification of external signal
    – Degree of PD Pulse deformation is identified through AI and automatically classified

Detailed Inspection of underground equipment (identification of PD occurrence circuit and external signal)

Inspection result

  • Occurrence of PD signal in PT
  • PD signal is flowing in from external devices connected to 3-circuit B phase
