This section presents the list of components from the EMTP libraries that are partially supported when the EMTP models are loaded in HYPERSIM. These blocks are compatible with an HYPERSYM simulation. However, some of their options are not supported in HYPERSIM. The first column indicates the name of the block in EMTP while the second column indicates the equivalent name of the component in HYPERSIM. The third column lists the options that are not supported in HYPERSIM.
