Automatic transformer oil tester DPA75 C , manufactured by BAUR (Austria) , is designed for automatic measurement of the electrical breakdown strength of insulating oils.

The breakdown voltage indicates the degree of contamination by foreign substances, such as cellulose fiber or water. The breakdown strength of the insulating liquid is an important factor in the operational reliability of a high-voltage oil-insulated device.

Functional features of DPA75 C:

• Ergonomic design
• Test voltage in the range 0 - 75 kV (rms)
• Thanks to the very short breakdown time (< 1 ms) and the presence of a current limiter, multiple measurements are possible on the same silicone oil sample
• Clear breakdown detection with RBM breakdown monitoring system
• Built-in sensor for measuring the temperature of electrical insulating liquid
• Built-in printer for automatic printing of test results and parameters (optional)
• Protective cover with locking device
• Oil-resistant keypad and easy-to-read graphic display
• Compact design, light weight
• Easy to transport via shoulder strap or handle (optional)
• Operation from mains or batteries (optional)
• Glass test vessel with lid
• Precise setting of the gap between the electrodes using a built-in calibrated vernier
• The vessel is made of durable glass and has a protective lid to prevent moisture from entering
• Electroacoustic control of setting the zero gap between the electrodes
• Cleaning the test vessel according to the specified procedure
• Large selection of electrodes and test vessels
• INCLUDED IN THE REGISTER OF MEASUREMENT INSTRUMENTS OF THE RF
