Portable Oiltester

The PORTATEST Oiltester is a fully automatic tester for determination of the dielectric breakdown voltage of insulating liquid. It has been designed for laboratory use as well as for field use for service and commissioning. The PORTATEST is very comfortable and easy in use. The requested testing standard may be selected via menu. The corresponding electrode type as well as the electrode spacing will be displayed for confirmation before starting the test.

After placing the test vessel with the oil sample into the test chamber, the protection lid needs to be closed. For maximum operator security the protection lid is equipped with a security interlock key switching off the HV when opened during testing. When starting the test, sample temperature as well as a customer specific sample number may be entered and will than be integrated to the test report printout. The testing sequence according to the selected testing standard is performed fully automatically.
