The present invention relates to a method for linearizing voltage transmission through a transformer including a magnetic core and, input and output windings. A measurement signal is supplied to the input winding at a first frequency and an output signal is measured at the output winding of the transformer, wherein the voltage of the measurement signal may be so low that the transformer operates in a non-linear region. The method comprises, for a conditioning signal, selecting a second frequency different from the first frequency (100), defining an amplitude value of the conditioning signal (110) and supplying the conditioning signal to the input winding at the second frequency with the defined amplitude value so that the transformer operates in its linear region (120).
