remote

Integrated control unit for the incoming feeder functional unit. It consists of an electronic relay with current sensors. Having full communications capabilities, it communicates with the remote unit for the remote control functions, and has the capacity for local control. • Detection functions • Phase to phase fault detection (TD Curve) • Phase to earth fault detection (NI, EI, MI and TD curves) • Voltage presence association • Digital filtering for magnetizing currents • Earth curve: inverse, very inverse and extremely inverse • Ultra-sensitive phase to earth fault detection • Presence / Absence of Voltage • Capacitive coupling (bushings) • Phase metering L1, L2, L3 • Voltage on the line itself (not LV) • Fault / Automatic sectionaliser • Capacitive and magnetizing currents • Switch monitoring • Switch-disconnector operation • Earth-switch monitoring • Switch failure • Switch disconnector control • Neutral directional detection
