Abstract
A housing part is configured to be connected to an electric component, to house an electric line, and to be filled with a liquid. The housing part includes an electrically conductive material and has an open mounting side to be connected to the electric component. A surface-to-volume ratio of the housing part is at least 3 m-1, and a ratio of the volume and a wall rupture pressure of the housing part is at least 0.02 m3MPa-1. A corresponding electric system is operated so that, when an electric arc occurs in the housing part, the housing part absorbs a pressure rise that is led into a component tank.
