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.
RED615 features genuine support for the IEC 61850 standard for communication in substations covering both vertical and horizontal communication, including GOOSE messaging with binary and analog signals and parameter setting according to IEC 61850-8-1. RED615 also supports the Modbus®, and the DNP3 and IEC 60870-5-103 protocols. RED615 offers an optional Ethernet port for self-healing communication in ring networks. The solution eliminates single point of failure concerns and improves the reliability of the communication. The solution can be applied for the Ethernet based IEC 61850, Modbus® and DNP3 protocols.
RED615 is a member of ABB’s Relion® product family and its 615 series.
