FIELD: electrical measurements.
SUBSTANCE: invention relates to the field of electrical measurements and can be used for remote measurements of impedance. The device for remote impedance measurement contains an auto-balance bridge from a measuring voltage generator, a voltmeter connected to this generator and controlling its voltage, a current-to-voltage converter from an amplifier with a resistive parallel negative feedback, and a vector voltmeter that measures the output voltage modulus of the amplifier and its phase shift relative to voltage measured by the mentioned voltmeter, two measuring clamps and two termination resistors with the same resistances, a connecting line of two identical coaxial cables connected to the measuring clamps at the input, a measuring cell at the output of the connecting line for connecting the measured object, containing two clamps electrically shielded from each other.
EFFECT: providing remote impedance measurement using connecting lines of almost any length from conventional quality cables, simplifying the measurement process.
