BDV.80KVS Triple‑Cup Transformer Oil BDV Tester

The BDV.80KVS is a fully automated dielectric breakdown voltage tester for insulating oils, designed in compliance with IEC 60156-1995, GB/T507-2002, DL429.9-91, and DL/T846.7-2004.

It is widely used in power networks, railway systems, and petrochemical plants where insulating oil dielectric strength must be tested to ensure safe operation of oil-filled electrical equipment.

The system is built around a single-chip microcomputer control platform, delivering high accuracy, repeatability, and user-friendly automation for modern laboratory and field applications.
