A fault detection device adapted for detecting an electrical fault at a medium voltage switchgear having at least one power module is provided. The fault detection device includes at least one input current sensor adapted for measuring at least one input current of the at least one power module of the medium voltage switchgear and at least one output current sensor adapted for measuring at least one output current of the at least one power module of the medium voltage switchgear. A comparator is provided which is adapted for comparing the at least one output current with the at least one input current. A control unit is adapted for determining an electrical fault at the at least one power module of the medium voltage switchgear on the basis of the comparison.
