FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering. The device for DC circuit condition monitoring containing the first and second power poles for formation of working voltage for DC circuit is offered; the first fuse (7a) connected to the first power pole, and the first fuse has a power pole (7a1) and the output pole (7a2); the second fuse (7b) connected to the second power pole, and the second fuse has the input pole (7b1) and the output pole (7b2); the device for formation of one or several reference voltages (UREFa, UREFb, UREFc); the device (3a, …, 3h, 3m, …, 3t) for formation of the first measuring voltage (U1a, U1b, U1c, U1d) between the output pole (7a2) of the first fuse and the power pole (7b1) of the second fuse; the device for formation of the second measuring voltage (U1a, U1b, U1c, U1d) between the output pole of the second fuse and the power pole of the first or second fuse; the device (4a, 4b, 4c) for comparison of one or several reference voltages and measurement voltages for assessment of condition of the first and second fuses; and the device (6) for indication of comparison result.
EFFECT: expansion of voltage range.
