Preventive maintenance - Hitachi ABB Power Grids organic products in a transformer degrade over time and finally they lose the capability to withstand the stresses a transformer might see in daily life (short circuits, energizing, vibration, etc.). It is possible to reverse the ageing of mineral oil through oil reclamation that can restore the material properties close to the values when new.
