DPA 75 C oil breakdown voltage tester The

The BAUR DPA 75 C oil breakdown voltage tester automatically tests the electrical breakdown strength of insulating liquids. Test sequences can be accomplished easily and fully automatically in compliance with all international and national standards. With reliable, informative test results it is possible to determine the exact condition of the insulating material and initiate any necessary measures, e.g. preparation of
transformer oil.
The high precision of the BAUR oil breakdown voltage testers is based on a tried and tested and very accurate test voltage measurement principle performed directly on the HV unit of the device, as well as the permanent monitoring of the voltage slew (RBM). The especially short switch-off time after a breakdown counteracts the
contamination of the oil sample, thus ensuring reliable reproducibility of the measurement results.
The DPA 75 C is designed especially for mobile use and for daily continuous operation in laboratories. The robust and sophisticated design guarantees safe and failure-free operation for several hundred thousands of oil sample measurements.
