FIELD: electricity.
SUBSTANCE: invention is related to measurement equipment, in particular to instruments for measurement of AC and DC with application of digital measurement equipment, mostly at voltages from 10kV to 1500kV. Digital device comprises current detector, analog-digital converter and modulator. Besides device is placed inside current conductor with measured current, is under potential of high voltage in zone of magnetic and electric fields absence. Current conductor with measured current is used as antenna-feeder circuit for transfer of modulated digital signal.
EFFECT: simplified design of instrument, reduction of weight and dimensional parametres, increased accuracy of measurements and reliability of operation in part of high-voltage insulation.
