Description
REF610 is a member of ABB’s Relion® product family and part of its 610 product series. The series includes protection relays for feeder protection, motor protection and general system voltage supervision. The plug-in design facilitates the commissioning of the switchgear and enables fast and safe insertion and withdrawal of protection relay plug-in units. REF610 is primarily intended for the protection of incoming and outgoing feeders in distribution substations of resistance earthed and solidly earthed power systems. REF610 is suitable for employment in marine and off-shore environments. Supplied with an optional arc protection function REF610 also provides fast substation busbar arc-fault protection. Scope • Feeder protection relay Product benefits • The compact design makes it suitable for both new and retrofit installations • Quick and easy routine maintenance thanks to the removable plug-in design • Complete type test certified by KEMA • Certificated for marine and off-shore use by Det Norske Veritas (DNV) Product features • Dedicated protection for utility distribution and industrial applications • REF610 offers overcurrent and thermal overload protection for cable feeders, non-directional earth-fault protection and phase discontinuity protection, and three-phase, multishot auto-reclose functions for overhead line feeders • REF610 supports a wide range of standard communication protocols, including IEC 61850, IEC 60870-5-103, Modbus®, Profibus, DNP3, SPA and LON.
REF610 is a feeder IED for protection, measuring andsupervision of utility and industrial distribution powersystems. REF610 is a member of ABB’s Relion® protectionand control product family and part of its 610 productseries. The 610 series includes IEDs for feeder protection,motor protection and general system voltage supervision.The plug-in design of the 610 series IEDs facilitates thecommissioning of the switchgear and enables fast andsafe insertion and withdrawal of IED plug-in units. Application REF610 is primarily intended for the protection of incomingand outgoing feeders in distribution substations of resistanceearthed and solidly earthed power systems. REF610 is suitable for employment in marine and off-shore environments.Supplied with an optional arc protection function REF610 alsoprovides fast substation busbar arc-fault protection. REF610sare also used for back-up protection of motors, transformersand generators to increase protection redundancy in criticalutility and industrial applications. Protection REF610 offers overcurrent and thermal overload protectionfor cable feeders, non-directional earth-fault protectionand phase discontinuity protection, and three-phase, multishot auto-reclose functions for overhead line feeders.Enhanced with an optional plug-in card the IED also offerstwo light detection channels allowing arc fault protectionof switchgear busbar systems and cable terminals.
Standardized communication REF610 supports a wide range of standard communicationprotocols, including IEC 61850, IEC 60870-5-103, Modbus®,Profibus, DNP3, SPA and LON. Disturbance recorder The 610 series IEDs feature an integrated disturbancerecorder for logging events and registering transient variablesbefore, during and after a network disturbance situation. The disturbance recorder includes four analog channels andeight binary channels, which can be assigned by the user tothe analog and digital signals requiring monitoring to enablesubsequent post-fault analyses of power system events. Supervision To ensure continuous availability of protection the 610 seriesIEDs feature extensive self-supervision of the function ofthe digital circuitry and the software. The IED also includesan integrated trip-circuit supervision function monitoring theexternal trip signal path. When a permanent IED fault isdetected, the IED’s protection stages and outputs will beblocked to prevent malfunction. Further, a LED indicator willlight up and an alert message for remote fault indicationwill be generated. Unique plug-in design The patented IED case and the plug-in type IED unit speedup installation, testing and maintenance of the device.A convenient pull-out handle with built-in release enablesquick removal of the plug-in unit and insertion of areplacement unit. The IED case is fitted with an automaticshort-circuiting mechanism to prevent hazardous voltagesfrom arising in the CT secondary circuits should an IED unitbe withdrawn from the case in live switchgear. When an IED plug-in unit is inserted into the IED case forthe first time, a mechanical coding system permanentlyadapts the case to the type of IED plug-in unit inserted.
