FIELD: electrical engineering.
SUBSTANCE: phase difference relay contains three threshold units, two pulse shapers, two OR elements, two executive elements, a clock-pulse generator, a counter, a balancing filter and a single-trip trigger.
EFFECT: extension of the relay functional capabilities due to output of a signal of inadmissible error of phases of two input signals with the error sign determined.
