Life Expectancy of Transformer Insulation System by Reconditioning

Reduction of waste oils and lubricants are indispensable because they are an important part of the volume of the organic waste generated worldwide. The recommended procedure for extending the lifetime of transformer oil is the reconditioning and reclamation process. The breakdown voltage test and the viscosity test of the transformer oil dielectric properties derived from the high vacuum purification process were investigated in this research. Varying transformer loading is represented as an increase in the temperature range from 30°C to 130°C. The test results of the breakdown voltage indicated that the reconditioning process increases the breakdown voltage value from 28.73 k V to 75.32 k V in the second round. The application of load variation on the transformer decreased the lifetime value of the transformer oil, but the reconditioning process was able to reduce the decline of from 0.01333% to 0.00889%.
