Modeling of three level surge protection device using EMTP-ATP

Abstract

In case of an atmospheric outbreak in the vicinity of low-voltage electrical installations, dangerous overvoltages are induced. Modern surge protection, which is used today in electrical installations, is the so-called three-stage protection. This paper will present the possibility of applying the ATP-EMTP software package for modeling and analyzing the operation of three-phase protection in electrical installations. The components of the three-stage protection will be modeled with the corresponding available characteristics.
