This report summarises the reasons of the necessity of performing arc fault tests and arc fault calculations for new hybrid AC&DC-grid concepts which are targeted in HYPERRIDE. It gives an overview about the normative references and describes the workflow of doing arc fault calculations and how to validate them with arc fault experiments. It describes the starting point for the physical model building which is necessary for both, the room average method and the Finite Element Method (FEM). The FEM-method use Computational Fluid Dynamics (CFD)and solves the Navier Stokes equations. First experimental results and a FEM calculation are discussed. A new enclosure is presented, which will be used in task T3.4 for performing systematic AC&DC arc fault experiments. The complicated physics of arcing requires a strong interaction of theory and experiments. Therefore a work flow for doing arc fault simulations in combination with arc fault experiments has been worked out.
