SPICE simulations of UWB pulse stressed protection elements against transient interferences

Abstract

This paper discusses the possibility of SPICE simulations of common protection elements against transient interferences by stressing with extremely fast high voltage ultra wideband (UWB) pulses. The focus of this investigation is the accuracy of the SPICE simulation relating to real measurements. Therefore different SPICE model implementations of protection elements are discussed also concerning numerical stability and complexity. Finally some UWB pulse effects on traditional protection elements are presented and discussed.
