Storm protection functions extend selected units of this series with a set of functions designed to indicate fault conditions in electrical grids. The functions can be used in modules (base units) and module assemblies (base unit + expansion module) with three-phase measuring transducer functions. The set of offered functions corresponds to the usual requirements for protective functions in three-phase electric grids of all voltage levels, different types of lines and ways of grounding the neutral point.
