A Study On The Detection Of Insulation Defect Location In A Cast-Resin Transformer Using Antenna Sensor
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.
