FIELD: electricity.
SUBSTANCE: invention is related to measurement equipment, in particular to method for measurement of AC voltage, mainly from 10 kV to 1500 kV. Method makes it possible to carry out accurate measurement of AC voltage with the help of divider with variation of measurement circuit parametres, using in voltage divider calibrated resistances only in low-voltage arm, besides high-voltage arm is arranged as inductive.
EFFECT: online measurement of high-voltage AC voltage with application of resistive divider, which does not depend on resistance of high-voltage arm, surface conductivity, leakage currents, atmospheric effects and inductive high-voltage arm.
