ABB FEEDER PROTECTION REJ601 NUMERICAL RELAY<\/h1>\n

Entry-level numerical relay for distribution networks ABB REJ601 Numerical relay is a dedicated feeder protection relay intended for the protection of utility and industrial power systems in primary and secondary distribution networks. The relay provides an optimized composition of protection and monitoring functionality in one unit, with the best performance and usability in its class.<\/p>\n

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.<\/p>\n

Scope<\/p>\n

Main protection for overhead lines and cable feeders in solidly earthed, resistance-earthed or isolated networks
\nInrush current stabilization function for distribution transformers<\/p>\n

    ABB Numerical relays are based on the use of microprocessors.\u00a0A 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.<\/p>\n
