In the power industry, the BDV (breakdown value/dielectric strength) of transformer oil is one of the most important indicators of insulation performance. Moisture, particles, aging products, and other contaminants can significantly reduce the BDV of insulating oil, increasing the risk of transformer failure and unexpected outages.
To help customers quickly and accurately evaluate oil condition, REXON provides a wide range of Automatic Oil Breakdown Voltage (BDV) Testers. These instruments automatically perform voltage boosting, oil stirring, breakdown detection, calculation, and result printing, allowing users to obtain reliable test results with minimal effort.
In fact, many customers who purchase our transformer oil purification machine also choose a BDV tester at the same time. By combining oil purification and oil testing, they can immediately verify the treatment results and ensure the oil meets operational requirements before being returned to service.
REXON currently offers the following 4 popular BDV tester models:
1. IIJ-II Automatic Oil BDV Tester (0~80kV / 0~100kV Optional)
A classic and widely used model featuring IEC-compliant testing procedures, automatic operation, and excellent anti-interference capability. It has a weather-proof covering, which is very suitable for outdoor project use. It can store up to 99 groups of test data and supports software upgrading through RS232 communication.
2. RTO Automatic Oil BDV Tester (0~100kV)
A premium digital model with a super large colorful touch screen, multiple international testing standards, temperature and humidity display, Chinese/English language switching, and highly accurate voltage sampling technology for superior measurement reliability.
3. RNJQ Automatic Oil BDV Tester (0~80kV)
A compact solution designed for routine transformer oil testing. It offers automatic testing, a large colorful touch screen, built-in thermal printing, data storage, and RS232 communication while maintaining excellent accuracy and ease of operation.
4. JKJQ Automatic Oil BDV Tester (0~80kV / 0~100kV Optional)
It's the most economical solution with higher voltage options, automatic test sequences, data storage, temperature monitoring, and safety protection functions. It is ideal for transformer manufacturers, maintenance contractors, and utility companies requiring flexible testing capabilities.
