摘要

Calculation methods are an important tool for the determination ofnpressure effects due to high current area in electrical installations.nIn this contribution an improved standard calculation method and a newnCFD-(computational fluid-dynamics) based method are introduced andncompared with two other existing methods. The fundamental physicalnphenomena are mentioned and their importance for the process of pressurenrise is explained. The calculation methods are discussed and it is shownnthat the relevant parameter for the application of one of thencalculation methods is the geometrical size. The application of thendifferent calculation methods is demonstrated with three typicalnexamples. The CFD-based method is applicable for all typicalnapplications whereas the improved standard calculation method is limitednto small size applications
