RED615 is a phase-segregated, two-end, line differential protection and control IED perfectly harmonized for overhead line and cable feeders in utility and industrial power distribution networks. The RED615s communicate between substations over a fibre-optic link or a galvanic pilot wire connection. Two RED615s interconnected over a communication link form an absolutely selective unit protection scheme. Protection of ring-type and meshed distribution networks generally requires unit protection solutions, also applied in radial networks containing distributed power generation
