A great deal of data about the transformer state can be determined from the results of analyses and operation parameters using indirect equations, diagrams and charts. Rezilabs usually offers the following methods free of charge to clients:

1. DP-Value by using Furfural Concentration
2. DP-Value by using Operating Parameters
3. Absolute Humidity in Cellulose
4. Relative Humidity in Oil
5. Gas Partial Pressure inside Transformer
6. Possibility Formation of Gas Bubbles
7. Oil Quality Index (OQIN)
8. Transformer Lifetime Remain
