AB - This paper confirmed the risk of oil immersed transformer through analyzing statistical data and other information. It classified the components by using the reliability evaluation software where FMEA (Failure Modes and Effects Analysis) technique can be applied, and used these to determine the failure mode and its percentages and derive the RPN (risk priority number) and criticality. The criticality of the components was found in insulation, insulating oil, tank and bushing for “H grade.” Insulation may be thermally decomposed and damaged due to mechanical stress, causing overheating or fire. In addition, when the abnormal operation of the coil occurs, the temperature of insulating oil rises and an abnormal sound is generated, which may cause an explosion or a power failure if overheated. Unlike the criticality analysis, the RPN of insulating oil is low due to the easy detection of abnormal sound and high temperature.
