Product Description

ABB FEEDER PROTECTION REJ601 NUMERICAL RELAY

Feeder protection REJ601

Entry-level numerical relay for distribution networks

REJ601 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.

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

Main protection for overhead lines and cable feeders in solidly earthed, resistance-earthed or isolated networks

Inrush current stabilization function for distribution transformers
