Abstract

The transformer is exposed to Very fast transient overvoltages (VFTOs) originated from the switching operations in the gas insulated switchgears (GIS), these overvoltages may damage the transformer insulation and result in catastrophic failures. Consequently, the transformer should be modeled to handle the transient state. In this work, the methods published in the literature to illustrate the VFTOs in GIS are reviewed, and then an overview of the transformer modelling techniques is presented with the contribution and shortcomings of each technique. The determination methods of the parameters required for the modelling of the transformer are also reviewed. In addition, the contributions of utilizing the frequency response analysis (FRA) as a diagnostic tool of the transformer condition are summarized.
