What It Assesses
The dielectric strength of the oil under the stated method and conditions.
Breakdown Voltage measures the oil's ability to withstand electrical stress under the specified test method. A reduced value may be associated with moisture, particles or contamination and can indicate the need for further investigation or corrective treatment.

Breakdown Voltage measures the oil's ability to withstand electrical stress under the specified test method.
Review the stated method, units, sample condition, companion tests and historical trend before making a condition judgement.
No single test result should be used as a universal diagnosis. Final maintenance, operational and safety decisions remain with the asset owner and qualified engineering personnel.
Provide the transformer details, sample count, reason for testing and any previous report reference so the exact scope and sample volume can be confirmed.
