What It Assesses
Acidic oxidation products present in the oil.
Acidity is an indicator of oil oxidation and degradation. Rising acidity can be associated with ageing products and may precede sludge-related concerns. Trend comparison is important because one result alone may not explain the full asset condition.
Acidic oxidation products present in the oil.
Acidity is an indicator of oil oxidation and degradation and is most useful when reviewed as a trend.
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.
