The BAUR DPA 60 C and DPA 75 C oil breakdown voltage testers measure the electrical breakdown strength of insulating liquids fully automatically. 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.
