Abstract

Liquid insulation is a vital medium in power system especially transformers which acts as insulation as well as coolant. As the year passed, the liquid insulation in transformer will degrade and start to lose its function as an insulation medium and this will affect the life and efficiency of transformer. The problem arises when the waste mineral oil is change to new mineral oil. Mineral oil in transformer can be potentially hazardous to the environment when occur accident during its working time. In order to prevent that from happen, vegetable oil is used as an alternative insulation liquid for transformer oil because it is more environmental friendly. In this work, waste cooking palm oil is reclaimed to replace mineral oil. Reclamation of oil is the process of removing contaminant using adsorbent and produce new oil that have almost same characteristic as new oil. This process is carried out by mixing and heating 1000 ml of waste cooking palm oil with 100 g of Fuller’s earth as an adsorbent for 4 hours before filtration to remove the used adsorbent. In this work, investigation of various parameters such as breakdown voltage, total acid number (TAN) and moisture content of different samples of cooking oil like waste cooking palm oil, new cooking palm oil, reclaimed cooking oil and antioxidant-reclaimed cooking oil using the standard of ASTM. From this experiment, it prove that the reclamation of waste cooking oil helps to improve the performance of this liquid insulation as its breakdown voltage, moisture content , and total acid number is reduced.
