DTA 100 C Oil breakdown voltage tester

The DTA 100 C fully 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.

Manufactory: BAUR (Austria).

Description

The DTA 100 C oil breakdown voltage tester has been specially designed for continuous operation in laboratories. The robust and sophisticated design guarantees safe and failure-free operation for several hundred thousands of oil sample measurements.
Features
  • Test voltages of 0 to 100 kVrms
  • Reliable, reproducible measurement results across multiple measurements thanks to short switch-off time < 10 μs
  • Clear breakdown detection by means of very precise measurement principle performed directly in the HV part and RBM technology
  • Fully automatic test sequences for 19 common test standards around the globe and spot tests
  • Easy creation of user-specific test sequences
  • Built-in sensor for measuring the temperature of the insulating liquid
  • Precise adjustment of standard electrode distances
  • Automatic self-test with HV output voltage test each time you start
  • EMC screen for preventing damage to electronic devices nearby
  • Comprehensive safety concept, incl. high voltage shutdown through hood contacts
  • User interface available in 14 languages
  • Illuminated test vessel
  • Ergonomic operating unit with oil-proof membrane keyboard, easy to read LCD colour display and integrated printer
