An arrangement for monitoring a condition of a direct current voltage circuit including first and second supply poles for forming an operating voltage. A first fuse is connected to the first supply pole, and has a supply pole and an output pole. A second fuse is connected to the second supply pole, and has a supply pole and an output pole. The arrangement can form one or several reference voltages (UREFa,UREFb,UREFc), can form a first measurement voltage (U1a,U1b,U1c,U1d) between the output pole of the first fuse and the supply pole of the second fuse, and can form a second measurement voltage (U1a,U1b,U1c,U1d) between the output pole of the second fuse and the supply pole of the first or the second fuse. One or several reference voltages and measurement voltages can be compared to estimate a condition of the first and second fuse, and a comparison result can be indicated. |
