Verification of Insulation Oil Reclamation by Turbidity and Spetrophotometry Measurements
Verification of Insulation Oil Reclamation by Turbidity and Spetrophotometry Measurements
摘要
Oil reclamation with Fuller＇s earth is known to have an improved effect on conditioning aged oil. In this paper it is shown that aged oil reclamation effectiveness can be monitored with turbidity and spectrophotometry measurements. These low cost testing techniques offer a useful tool to quantify the effect of Fuller＇s earth. Experimental investigations performed in laboratory conditions have shown that the quality of properly reclaimed aged oil can compete with that of new oils. Thus, in addition to extending the life cycle of this non-renewable resource, on-line reclamation of liquid might also prevent the premature ageing of paper insulation. Studying the stability of reclaimed service aged oil samples emphasized the important role played by Fuller＇s earth absorption capability.
