要約(英語): When a fault arc occurs in an electrical installation, the pressure in it increases due to the energy input from the arc into the gas. With surrounding equipment and personnel safety in mind, the properties of the pressure rise and propagation must be clarified. For this purpose, internal arc tests for electrical installations have been carried out. However, the testing conditions are so wide ranging that a lot of effort and cost will have to be consumed. Since this is inefficient, it is desirable to find a way to calculate the pressure rise and propagation. This paper describes the trend of calculation technology of pressure rise and propagation in electrical installations due to fault arcs, where the arcs are generated in air or SF6 or oil that is the main insulating material in electrical installations.
