YNHYG-A
IEC 60156 Transformer Oil BDV Tester
- The YNHYG-A IEC 60156 Transformer Oil BDV Tester is an automatic breakdown voltage testing instrument designed to measure the dielectric strength of transformers and other insulating oils.
- By applying a controlled AC voltage between electrodes immersed in an oil sample, the tester determines the voltage at which electrical breakdown occurs.
- With automatic microcomputer control, a standard 2.5 mm electrode gap, and up to 80 kV output voltage, it provides repeatable BDV measurements for transformer oil condition assessment and maintenance.
IEC 60156 Transformer Oil BDV Tester Features
- The instrument is controlled by a large-capacity single-chip computer, which is stable and reliable;
- A wide-range watchdog circuit is installed in the instrument to prevent crashes;
- A variety of operation options, which can adapt to multiple choices of different users;
- The instrument oil cup is made of special glass by one-time casting, which prevents the occurrence of interference phenomena such as oil leakage;
- The unique high-voltage side sampling design of the instrument allows the test value to directly enter the A/D converter, avoiding errors caused in the analog circuit, and making the measurement results more accurate;
- The instrument has protection functions such as over current, over voltage, short circuit, etc., and has strong anti-interference ability and good electromagnetic compatibility;
- Portable structure, easy to move, very convenient for indoor and outdoor use.
