Abstract

Liquid insulation is a vital medium in power system especially transformers which acts as insulation as well as coolant. As the year passed, liquid insulation in the transformer degrades and begins to lose its function as an insulation medium, which affects the transformer's life and efficiency. The problem occurs when the waste oil is converted into new mineral oil. Mineral oil in transformers can affect the environment if accidents occur during working hours. The decision of replacing, refurbishing or repairing a service aged power transformer requires considering several factors, especially the cost and time to execute the work. 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. Catalyst which is sodium hydroxide (NaOH) content is analyzed for WCO methyl ester transesterification. In addition to analyzing the differences in the sequence between recycling and transesterification in an opportunity to impact the oil quality improvement process. The study are carried out to verify the results using the optimum reclamation process parameters, it is found that there is significant improvement in the AC breakdown voltage, total acid number (TAN), moisture and Ultraviolet-Visible (uv-vis) for the reclaimed transformer oil. This method is believed to be an independent tool for determining the optimal parameters for the recovery process for methyl ester waste oil.
