The equipment consists of a system to monitor three-phase 69 kV sub-transmission lines using a set composed of up to six sensoring units and a concentrating unit called Remote. It can detect Transient fault per phase and group; Permanent absence per phase and group; Reclosing and Shutdown (per phase); Current surge; Neutral overcurrent; Inverted sensor; Flow inversion; Current (RMS per phase); Module and angle phase A, B and C; Neutral module (resulting current); Communication failure between-group equipment; Neutral angle (resulting current); Low voltage alarm of
ultracapacitors; Loss detector, among others.
