FIELD: measurement equipment.
SUBSTANCE: invention relates to measurement equipment and represents a linearisation method of voltage transfer through a transformer, which includes a magnetic core and input and output windings. A measuring signal is supplied to the input winding on the first frequency; an output signal is measured on the output transformer winding, with that, voltage of the measuring signal can be so low that the transformer operates in a non-linear region. At implementation of the method, the second frequency is chosen, which differs from the first frequency, for a matching signal; an amplitude value of the matching signal is set and the matching signal is supplied to the input winding on the second frequency with the specified amplitude value so that the transformer can operate in its linear region.
EFFECT: improvement of the method.
