Feeder protection and control ABB REF601 numerical relay Entry-level numerical relay for distribution networks REF601 is a dedicated feeder protection and control relay intended for the protection and control of utility and industrial power systems in primary and secondary distribution networks. The relay provides an optimized composition of protection, monitoring and control functionality in one unit, with the best performance and usability in its class. Besides the conventional current transformer interface based variant, the relay also supports a variant based on Rogowski current sensors analog interface. This helps to obtain a compact medium voltage switchgear equipment size reduction with improved performance and standardization.
Scope

ABB Numerical relays
ABB Numerical relays are based on the use of microprocessors. A big difference between conventional electromechanical and static relays is how the relays are wired. Electromechanical and static relays have fixed wiring and the setting is manual. Numeric relays, on the other hand, are programmable relays where the characteristics and behavior can be programmed. Most numerical relays are also multifunctional.
