Two-line-ends differential protection relay ABB Oy Distribution Automation
RED615

RED615, member of ABB's 615 product series, is a phase-segregated two-end line differential protection and control IED perfectly harmonized for utility and industrial power systems, including looped and meshed distribution networks with or without decentralized power generation. Re-engineered from the ground up, the new 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation equipment.

RED615 provides phase-segregated high speed, longitudinal differential protection for overhead line and cable feeders in distribution networks. 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.

Due to the ready-made adaptation of RED615 for the line differential protection, the IED can be rapidly set up and commissioned, once it has been given the application-specific IED settings. If the IED needs to be adapted to the special requirements of the intended application, the flexibility of the RED615 allows the IED's standard signal configuration to be adjusted.
