ABB 3Feeder Protection and ControlREF615Product version: 2.01MRS756379 DIssued: December 2007Revision: D / 03 Mar 20091. DescriptionREF615, member of ABB’s 615 productseries, is a dedicated feeder protection IEDdesigned for the protection, measurementand supervision of utility substations andindustrial power systems. Re-engineered fromthe ground up, the IED has been guided bythe IEC 61850 standard for communicationand interoperability of substation automationdevices.The IED provides main protection for over-head lines and cable feeders in distributionnetworks. The IED is also used as back-upprotection in applications, where an inde-pendent and redundant protection system isrequired.Depending on the preconfiguration made,the IED is adapted for the protection ofoverhead line and cable feeders in isolatedneutral, resistance earthed, compensated andsolidly earthed networks. Once the standardconfiguration IED has been given the appli-cation-specific settings, it can directly be putinto service.The 615 series IEDs support a range of com-munication protocols including IEC 61850with GOOSE messaging, IEC 60870-5-103,Modbus® and DNP3.2. StandardconfigurationsThe feeder protection IED REF615 is availablewith six alternative standard configurations.The table below indicates the functions sup-ported by the different IED configurations.Table 2.
