Electromechanical relay / protection / control / FEEDER protection

Relion® REF630 IED is constructed to be world-class for managing utility and distribution substations. It is built to protect, manage as well as measure and supervise at the feeder-level with the control function feature.

The function portfolio is comprehensive and can be programmed for four pre-stated feeder levels. The factory-settings can also be tweaked for end-use requirement, with the add-on select functions.

Relion® REF630 is built to monitor five qualities of power - Voltage variation, unbalance, harmonics as well as voltage harmonics features. The winning feature for this equipment, however, is the Fault Location function, which identifies short circuits.
