RMS7992 / RMST7992 – Overcurrent Relays
Products family : Feeder Protection, Current Protection
Sector : Industry
The optimum operation of an electrical network depends particularly on the reliability and the availability of the protection, measuring and automation devices, and the waythese devices can communicate their informations.
RMS 7992 relays are designed to provide protection of three phase networks against any kind of short-circuit between phases or between phase and earth.
– RMS 7992 relays protects of all types of electrical power equipement, and most specifically transformers and plain feeders.
– RMST 7992 relay has a thermal image measuring unit designed for power transformer and feeder overload protection.
