The oil breakdown voltage testers are portable, automated devices designed for testing the breakdown voltage of transformer oil and other liquid dielectrics, in line with IEC 60156, VDE 0370, ASTM D877, ASTM D1816 standards, as well as user-defined procedures in the unit’s menu.
The test sequences are simple to perform and fully automatic, meeting all relevant international and national standards. With accurate and detailed results, these testers provide a clear assessment of the insulating material’s condition.
The quick switch-off time after a breakdown helps prevent contamination of the oil sample, ensuring consistent and reliable results. These testers are built for mobile use and continuous daily operation, whether in the field or in laboratories. Their robust design ensures safe and reliable operation, even after thousands of measurements.
