FIELD: electricity.
SUBSTANCE: arrays of instantaneous current and voltage values for three phases are measured at the beginning and end of the line for the same time moments. Signals are transmitted from the end of line to its beginning via communication channel. The pairs of digital readouts are saved as the current ones and the respective vector values are generated to be used for generation of vector values for symmetrical positive-sequence voltage and current components in the phase A in the beginning and end of the line
EFFECT: increased accuracy of phase loss spot detection.
