Abstract : Unlike oil-immersed transformers, cast-resin transformers have the solid insulator ‘epoxy resin’ in sealed structure. Therefore, they reveal a lot of limitations in checking aging conditions and predicting an accident. This study analyzed the characteristics of Cast-resin transformers by the measurement distance and measurement sensitivity with a corona defect sample, using antenna sensor. Therefore, the experiment has proven that the antenna sensor-based measurement method proposed in this study is able to detect the insulation defect location of the cast-resin transformer, unlike conventional measurement methods. Index Terms- Fault Location, Partial Discharge, Cast-resin Transformer, Antenna Sensor.
