Abstract: A protection system for an electrical machine includes a first connecting line for connecting an internal space of the electric machine to an external space surrounding the electrical machine, a valve, and a filter which is impermeable to dust. The valve and the first connecting line are configured to render the first connecting line impassable when the valve is closed, and to enable a first gaseous medium to enter the internal space from the external space when the valve is open. The filter is configured to filter the first gaseous medium that enters the internal space from the external space through the first connecting line.
