Oil BDV Tester
The Greenwatt Oil BDV Test Kit (GW-OBDV A+) is a fully automatic instrument for measuring the dielectric breakdown voltage of transformer and insulating oils. It applies a precisely controlled rising voltage between standard electrodes until breakdown, runs a complete multi-shot sequence with automatic stirring and rest periods, and computes the result — to international standards including IEC 60156, ASTM D877, ASTM D1816 and VDE.
Key Features
- Fully automatic sequence — runs the complete multi-shot test with programmable stirring and rest times, then computes the result
- Multi-standard testing — pre-loaded routines for IEC 60156, ASTM D877, ASTM D1816, VDE 0370 plus user-defined methods
- Programmable rate of voltage rise and number of breakdowns per sample for accurate, repeatable results
- Built-in magnetic stirrer homogenises the sample between breakdowns for representative readings
- Statistical results — automatic average, standard deviation and individual breakdown values per run
- Operator safety interlock — high voltage cuts the moment the lid is opened, with auto-discharge
- Built-in thermal printer and data storage with oil temperature display
Applications
- ›Transformer oil testing
- ›Power utilities and substations
- ›Oil filtration and reclamation plants
- ›Switchgear and cable oil testing
- ›Testing and calibration laboratories
- ›Manufacturing and maintenance
