OC60E Fully-Automatic 60kV AC Liquid Dielectric Test Set














Testing of transformer oil with the OC Series of Oil Dielectric Testing Equipment has just became simpler. One of Hipotronics latest developments, the OC60E, includes an integrated control and data acquisition system in the same package. The new controller allows the user to quickly perform reliable tests regardless of whether it is from the standards or just a quick dielectric test.

The test results are displayed on a 20 x 4 STN liquid crystal display. Data from standard tests is automatically stored in one of 25 internal memory slots make report generation and storage of acquired test data simple. When stored, the test data can be downloaded to a computer using the RS-232 port and a desktop Utility program on your PC.

The OC60E is a fully automatic digital liquid dielectric test set designed to reliably and accurately test the dielectric strength of insulating liquids. The OC60E controller is pre-programmed with test procedures to automatically perform ASTM D877, ASTM D1816 and IEC 156 specified tests.




  • Pre-programmed with standard test profiles..
  • Rugged and reliable.
  • Test sequences are easily upgradeable as standards change.
  • Storage of the last 25 tests.
  • Output voltages to 60kV AC.
  • Tests insulating oils per ASTM and IEC standards.
  • Automatic high voltage shutdown at breakdown.
  • Digital memory kilovoltmeter.
  • Meter accuracy 2% of full scale.
  • One piece construction with safety interlocked high voltage section.


  • Multi-purpose - because of its compact design its easily useable in the field as well in the factory.
  • Sturdy and reliable - the OC series of testers have a long and trouble free life, proven by over 40 years of industry wide use.
  • Safe and easy - The interlocked high voltage section and integrated controller allow your operators to test safely and easily.
  • Report generation - with the optional printer or using the standard
    RS-232 port, test report generation is made simple.
  • Additional Parameters - The user has the ability to enter additional test parameters such as temperature or viscosity.
  The safe and easy operation of the OC Series from Haefely Hipotronics has made it the industry standard for more than 40 years. It's rugged yet lightweight design ensures years of trouble free operation in both the field and the factory. The OC60E automatically terminates the voltage upon sample breakdown and the digital memory kilovolt meter automatically retains the breakdown voltage reading.
