The efficient simulation of the current interruption phase in high-voltage circuit breakers is routinely performed based on integral models for the gas dynamics and the arc physics. We present a Modelica framework for such a model. Based on Modelica.Media, a thermodynamic library for the required temperature and pressure range has been developed. Making use of the latest Modelica.Fluid library and the new streams concept, a library for the gas dynamics and the arc physics in such systems has been implemented.
