Development of a Current impulse data base for ZnO Surge arrester models analysis

The correct and adequate modelling of ZnO surge arresters characteristics is fundamental for various routine studies performed on electrical systems, such as insulation coordination and systems reliability studies. In this context, many researchers addressed considerable efforts to the development of models to reproduce the behaviour of the equipment. Only a few of these proposed models are based on actual measurements of the surge arresters behaviour, mostly they are based and validated with data acquired through bibliographic research, meaning most of the developed models are based and analysed with a small database. Recent papers indicate that most measurements used to propose models of surge arresters are strongly affected by the inductance of the measurement set up, therefore the…
