Abstract
An assembly includes an electrical machine connected to a power converter by a three-phase circuit having three conductors, e.g. cables Each conductor is associated with a switching device such as a contactor or the like that connects the conductor to a common conductor or terminal. In the event of a fault current being developed in the circuit or the power converter the switching devices are operated to close the fault current and connect together the conductors of the three-phase circuit to provide a full three-phase short circuit.
