Furthermore, the power supply device (10) comprises a first measuring device (20) for monitoring an insulation resistance between the connection device (12) and the ground of a first type (16). Moreover, the power supply device (10) comprises a further measuring device (22) for monitoring an insulation resistance between the ground of a first type (16) and the ground of a second type (18). The further measuring device (22) thereby comprises a plurality of measuring lines (24), of which a first measuring line (26) is electrically connected to a first potential (32) of a power source of a second type (30) and of which a further measuring line (28) is connected to the ground of a second type (18).",
