How often should transformer oil be filtered?

According to the testing specifications of transformer oil, the transformer oil in operation should be tested for oil quality analysis every time, and whether it is necessary to replace the transformer oil is considered according to the results of the testing and analysis or the operating state.

According to the service life of the transformer, through the latest comprehensive analysis of the transformer oil insulation resistance, absorption ratio, polarization index, dielectric loss, winding leakage current, slight water in the oil, etc., comprehensively judge the moisture condition, impurities, oil aging, etc. If it is not qualified, you need our DVTP Transformer Oil Purifier Plant for oil purification and continue to use. If it is not available for oil regenerate in special circumstances, you can also consider replacing with new transformer oil.

Generally speaking, dissolve gas analysis of transformer oil needs to be done annually for 132kV transformer, once in 2 years for the transformer below 132kV transformer, and once in 2 years for the transformer above 132kV transformer.
