What It Assesses
The interfacial behaviour of oil under the specified method.
Interfacial Tension helps assess the presence of polar contaminants and oxidation products in insulating oil. When reviewed together with acidity, colour and other test results, IFT can provide useful evidence of oil ageing and deterioration.
The interfacial behaviour of oil under the specified method.
IFT helps assess polar contaminants and oxidation products when reviewed with acidity, colour and other data.
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.
