SME70-O (RGDAT OUTDOOR)

Secondary MV protection

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.
