The article investigates the dynamic characteristics of the new electromagnetic transducer of the asymmetry of three-phase currents and the difference in direct currents. It is shown that when a jump-like differential current is applied to the input of a transducer operating in a magneto modulation mode, its transient response at the output of one measuring winding consists of the sum of one steady-state and two free harmonic components with a frequency equal to double the modulation current frequency, the free components of which decay with speeds , depending on the values of the time constants, respectively, of the measuring and modulation magnetic circuit, and when a pulsating differential current with a frequency is applied to the input of the converter, the transient response consists of the sum of one harmonic steady-state component with a frequency equal to the modulation current frequency and two harmonic free components with frequencies equal to  and , respectively, and decaying at rates depending on the values ??of the time constants, respectively, of the measuring and modulation magnetic circuit. It has been established that when a three-phase current is fed to the input of a transformer operating in a transformer mode, its transient response at the output of one measuring winding consists of the sum of the established sinusoidal and free component, which decays at a rate that depends on the value of the time constant of the magnetic circuit of the transformer.
