FIELD: electricity.
SUBSTANCE: current relay contains an intermediate current transformer, a rectifier, an actuator, four threshold blocks, two AND elements, a reversing counter, a single vibrator, a clock generator, a frequency divider, a subtracting unit, an adder, a limiter, a nonrecursive filter.
EFFECT: invention makes it possible to increase the noise immunity of the current relay under conditions of short-term anomalous distortions of the input signal.
