Two-line-ends differential protection relay
ABB Oy Distribution Automation
Relion® 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. Three standard RED615 configurations are available, a pure line differential protection configuration with overcurrent back-up stages and two extended configurations with additional protection functions.
