PURIFICATION OF TRANSFORMER OIL in PT. PJB UP PAITON

The purpose of this paper is to describe the filtration or purification of transformer oil. One of the main equipment in coal-fired power generation unit is transformer. When the transformer fail to operate properly, the continuity of distribution system become interrupted. As a part of transformer, transformer oil contribute the failure of transformer due to the aging. To solve this problem, several methods is applied starting from dehydration process, degasification process, oxidation removal and filtration or purification. After the purification process is performed, the transformer oil then analyzed. The result shows that the purified transformer oil is better than before purified.
