7SG118 Argus 8 voltage and frequency relays are numerical, multi-function devices that are designed to be applied for the protection of transmission, distribution and industrial systems.
The relay provides phase under and over voltage, neutral displacement overvoltage, negative sequence overvoltage and under and over-frequency protection elements.
These relays have extensive protection functions, which are supplemented by advanced metering, data storage and communications. Supervisory and self monitoring features give added confidence to the user as well as reduced maintenance and down time. A menu-based interface gives user-friendly access to relay settings, meters and operational data.
