Abstract

Short-circuits in electrical networks come along with severe mechanical and thermal stresses not only to loads and systems, but also to the installed protection devices. Combined analytical simulations have been performed for analyzing and optimizing the behavior of low-voltage circuit-breakers. Especially circuit-breakers with electronic tripping units have been scrutinized.
