Recovery Voltage Modelling of Transformer Insulation

Recovery Voltage is a phenomenon of polymeric insulators. It is believed to have close relationship with the aging state and moisture content of the insulator. However the interpretation of the measurement is still open to debate, therefore the aim of this project is to study the relationship of measurement with relevant parameters under controlled environment. This will then lead to a model that will be applicable in actual transformer diagnosis.
