Abstract. The article justifies the choice of the measuring transformer using the scheme "modulator - demodulator" on the basis of the magnetic-modulation transformer for the transducer of the intensity of electric fields generated by oceanic turbulence within frequency range below 1 Hz. The author analyzes the factors influencing the intrinsic noises of the magnetic-modulation transformer, evaluates their impact on the transformer threshold sensitivity. The researcher has received analytic expressions to identify the metrological characteristics of such transducers.
