Earth-fault detector SME70-O

SME70-O fault detection system is designed in conformity with the ENEL GSTP001 specification; it is installed in outdoor application in order to provide local and remote signalling of short circuit and earth faults that may occur in MV distribution networks. SME70-O quickly locates the line section affected by the fault thus reducing power outage. STANDARD PROTECTIVE & CONTROL ELEMENTS • Positive Sequence Undervoltage • Phase overcurrent side H and side L • Maximum Residual Overcurrent • Negative sequence overvoltage • Ground directional overcurrent • Overvoltage • Residual Overvoltage • Modbus RTU RS232 protocol
