FREQUENCY-PHASE RELAY Russian patent published in 2004 - IPC

Abstract RU 2237311 C1

FIELD: electrical engineering, used for production of electronic frequency relays, for example, at an adjustment of the frequency relays, for example, at an adjustment of the frequency and phase of the generator at its connection to the circuit.

SUBSTANCE: the frequency-phase relay has two frequency-dependent elements, adder, actuating element, seven threshold units, three AND gates, reversible counter, clock-pulse generator, one-shot multivibrator, algebraic adder, inverter and a multiplier.

EFFECT: expanded functional potentialities.
