FIELD: electrical engineering. SUBSTANCE: invention is intended for use as synchronization relay in lines of bilateral power supply when disconnection of line is accompanied with fall out of synchronism. Proposed synchronization relay incorporates instrument converter, four comparators, final-control element, generator of clock pulses, univibrator, former of short pulse by trailing edge, storage register, two AND gates, OR gate, delay element, pulse counter. EFFECT: increased precision of synchronization relay. 2 dwg
