The transformer is an electrical equipment that functions to change the voltage of alternating current from one level to another. Inside the transformer, especially the power transformer, there is transformer oil which functions as a coolant which transmits heat to the fins of the transformer as well as an arc extinguisher in case of sparks in the transformer windings. Transformer oil is generally obtained from petroleum which is decreasing over time and is less environmentally friendly so that other alternatives are needed to overcome it. This research on the feasibility of ketapang seed oil as a liquid transformer insulating material is intended to determine the feasibility of ketapang seed oil based on the permitted used transformer oil specifications (SPLN 49-1: 1982 and IEC 60296: 2012). This test is carried out by several types of tests, namely testing the moisture content, density, viscosity, and testing the oil breakdown stress. From the test results, it was obtained that the water content of ketapang seed oil was 10 mg/kg, the density value was 0,921 gram/cm3, the viscosity value was 14,665 cSt and the breakdown stress value was 68,9 kV. From these results, based on the new transformer liquid insulating oil specifications, ketapang seed oil still does not meet the standards seen from the density value of the oil.
