On-site Test for IEC 60156 Breakdown Voltage

Category: Laboratory

We provide on-site testing for IEC 60156 Insulating liquids-Determination of the breakdown voltage at power frequency.

This test method covers the determination of the breakdown voltage of the insulating oil. This test method applies to insulating oils commonly used in cables, transformers, oil circuit breakers, and similar equipment as an insulating and cooling medium.

Our equipment can be used for: ASTM D 1816, ASTM D 877, IEC 60156.


Transformer oil that serves as insulation and coolant must be tested periodically to ensure that the oil functions as intended. The breakdown voltage measurement is one of the tests that can be used to see the quality of transformer oil. The lower the value of the resulting breakdown voltage, it indicates a decrease in oil quality that is getting worse.
