Earth-fault detector SME2-I

Indoor fault detection device with functions: maximum current, earth directional, maximum active power directional, reclosing, presence/absence voltage and synchronism control. STANDARD PROTECTIVE & CONTROL ELEMENTS • SynchroCheck • Directional active overpower • Phase reversal • Phase overcurrent side H and side L • Maximum Residual Overcurrent • Phase Directional Overcurrent (Voltmetric Permission) • Automatic Recloser • One Ethernet local RJ45 port for communication with ThyVisor setup software • One Fibre Optic Ethernet port dedicated to IEC 61850 Homopolar quantities are obtained by means of vector calculationfrom the measurement of phase currents and voltages.Two Ethernet communication ports are available, one of whichwith IEC61850 protocol.This protocol allows you to use a single field bus that has all thenecessary features for controlling the electrical system and process control with the significant advantages of: • belonging to an international standard • update speed of the transmitted variables • high communication reliability. In order to ensure full compatibility with the RTUs already presenton the Secondry systems, the SME2-I device is equipped with adouble interface, capable of being able to communicate with boththe UP (DX1215) and future communication devices.
