This paper presents the CFD calculation results of the pressure rise due to the High Energy Arcing Faults (HEAFs) in the cable compartment of the metal-clad switchgears. The calculations were carried out considering the propagation of the hot gases from the cable compartment to the outside and the came-off of the compartment roof panel that was observed in the arc tests. The calculated pressure development was in good agreement with the measured one.
