BAUR DPA 75 C Insulating Oil Tester: Portable, Accurate & Economical

The BAUR DPA 75 C makes evaluating transformers and other dielectric fluid-filled equipment through proper insulated oil testing easier, more accurate and more economical than ever before. Unique in the market due to its precision, functionality, lifetime of use and value, the DPA 75 C is developed especially for mobile usage. It provides clear, reliable and reproducible measurement results. Due to its lightweight design, the DPA 75 C is particularly handy, easy to operate and excellent under tough ambient conditions. Key features include:

• Fully automatic measurement of the dielectric strength of insulating oil up to 75 kV
• Integrated battery with long operation time out in the field
• Clear and reliable results through the latest measurement technology (“Real Breakdown Monitoring”)
• Repeatable breakdown measurement in mineral, silicone, and natural ester fluids
• Modern and robust design for laboratory or onsite testing

The breakdown voltage test with the DPA 75 C oil tester is used to evaluate the degree of impurities in insulating fluids due to foreign particles and water. It meets current regulations and helps to protect electrical systems, such as transformers and switchgear, from failures, extending their lifespan. 

FACTS:

• Test voltages up to 75 kV
• Ergonomic design for high efficiency, usability and safety
• Mains or battery operated with internal, rechargeable batteries
• Battery run-time of up to one full working day for mains independent continuous use onsite
• Switch-off time below 10 microseconds for reliable and reproducible results over multiple measurements
• Clear breakdown detection with measurement principle directly on the high voltage side
• Repeatable breakdown measurements even on silicone oils and ester fluids
• Automatic self-test with HV output voltage test
• Fully automatic measuring sequences from 18 pre-programmed test standards and 10 user-programmable test sequences, including ASTM D1816 and D877
• Oil-proof membrane keyboard, easy to read LCD color display, and integrated printer
• Built-in sensor for temperature measurement of the insulating fluid
• High quality glass test vessels 
• EMC shield to prevent damage to IT infrastructure

Optimum Data Management Possibilities

Proper archiving of the measurement results is essential for the analysis of insulating fluids. The DPA 75 C allows 3 different possibilities to archive the results:

1. Integrated printer for immediate print out of the results
2. ITS Lite Software (download here): allows structured storage of measurement results in .pdf and/or .txt files on any PC/laptop that is connected to the DPA 75 C via USB cable. This is ideal for use in a laboratory environment.
3. Report Manager: allows automatic storage of measurement results in .pdf and/or .txt files on an external device that can be exported at a later time using an USB stick. Ideal for when using the DPA 75 C as a mobile device in the field.
