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.
