FIELD: measuring technique.
SUBSTANCE: device comprises direct high-voltage divider, reference composed direct voltage divider made on the basis of resistive elements, and two-row voltage comparator. The reference composed direct voltage divider has high-voltage arm composed of three nominally equal closed resistive elements and output arm for permitting alternative switching-off of the resistive elements of the high-voltage arm and change of conversion factor of the divider .
EFFECT: simplified design.
