An assembly includes an electrical machine (2) connected to a power converter (6) by a three-phase circuit (8) having three conductors, e.g. cables (10a, 10b, 10c). Each conductor (10a, 10b, 10c) is associated with a switching device (14a, 14b, 14c) such as a contactor or the like that connects the conductor to a common conductor (16) or terminal. In the event of a fault current being developed in the circuit (8) or the power converter (4), the switching devices (14a, 14b, 14c) are operated to close the fault current and connect together the conductors (10a, 10b, 10c) of the three-phase circuit (6) to provide a full three-phase short circuit. |
