Abstract

Transformer is a device which is critical, high in load and the most expensive part in generation and distribution system. Transformer oil is used as the medium for insulation to avoid the transformer produce more heat due to the process of energy transfer. Most of factor that contributes to the transformer failure is the physiochemical reactions such as heat, oxygen and moisture content had effect the transformer oil. So, there will be increment in terms of water content and total acid number for the transformer oil. Then, this will affect breakdown voltage (BdV) of the oil which make the BdV decrease. Therefore, this project was conducted in order to produce a new oil from the used oil of a transformer. In order to justify the oil is suitable for transformer operation, Karl Fischer, Total Acid Number (TAN) and BdV test will be used to observe the changes in terms of water content, acid number and breakdown voltage of the reclaim oil. Standard of ASTM D1816-84a will be used as the guidelines in the testing BdV procedure and confirmation of the finding. The result will be shown the effect of multiple stage of reclaim oil to the performance of the oil in terms of water content, total acid number and breakdown voltage. By using Karl Fischer and TAN test, total of water content and acid number which able to remove must be more than 50%. Other than that, BdV test should increase the value of breakdown voltage for multiple stage of reclaim oil more than 50%. So, it will expect to get the improvement for dielectric strength on used transformer service oil for reclaimed oil.
