AB - This study performs safety assessment of oil immersed transformer through the FTA (free tree analysis) method. Top events are detected along with their risks for each safety device, which is classified into the components, using the reliability evaluation software where FTA is applicable. The safety device of oil immersed transformer may cause overheating and fire of insulating oil due to the thermal characteristics shown as electrical energy of coils 1 to 3. In addition, in case of the unusual operation of the coil, the temperature of insulating oil may rise along with an unusual sound, which may cause an explosion or blackout if overheated. Thus, the management of safety devices responsible for temperature and pressure of insulating oil is very important. This study designs a functional block diagram for the safety devices of six dial thermometers, oil level gauge, auto-resetting pressure, pressure gauge, B-H relay and pressure relief vent. An FT diagram was drawn and analyzed through a designed functional blockage diagram.
