Transformer Oil Analysis

Transmission Network Operators must ensure that oil-filled power apparatus remains in peak performance with optimum efficiency at all stages of the asset’s life. Key to achieving this is regular testing of the oil to evaluate its condition and to ensure it has the correct properties to serve its purpose as an insulator and coolant.


Oxidation, moisture and temperature all present issues for transformer oil. EMT provides laboratory standard transformer oil testers and oil testing sets to analyse the fundamental characteristics of insulating oil.

Sampling the oil in transformers using the H20P Portable Moisture in Oil Meter from EMT, provides valuable information on the condition and properties of the oil. 

An increase in TAN value can have negative effects on assets in electric power utilities. The determination of acidic constituents in transformer insulating oils, and asset health indicators are provided by the TAN acidity in oil meter from EMT.
