ABB RED670 Integrated protection relay

  RED670 is used for the protection, control and monitoring of overhead lines and cables in all types of networks. The IED can be used from distribution up to the highest voltage levels. It is suitable for the protection of heavily loaded lines and multiterminal lines where the requirement for tripping is one-, two-, and/or three-phase. The IED is also suitable for protection of cable feeders to generator block transformers. The phase segregated current differential protection provides an excellent sensitivity for high resistive faults and gives a secure phase selection. The availability of six stabilized current inputs per phase allows use on multi-breaker arrangements in three terminal applications or up to five terminal applications with single breaker arrangements. The communication between the IEDs involved in the differential scheme is based on the IEEE C37.94 standard and can be duplicated for important installations when required for redundancy reasons. Charging current compensation allows high sensitivity also on long overhead lines and cables. A full scheme distance protection is included to provide independent protection in parallel with the differential scheme in case of a communication channel failure for the differential scheme. The distance protection then provide protection for the entire line including the remote end back up capability either in case of a communications failure or via use of an independent communication channel to provide a fully redundant scheme of protection (that is a second main protection scheme). Eight channels for intertrip and other binary signals are available in the communication between the IEDs. A high impedance differential protection can be used to protect T-feeders or line reactors. The auto-reclose for single-, two- and/or three phase reclosing includes priority circuits for multi-breaker arrangements. It co-operates with the synchronism check function with high-speed or delayed reclosing. High set instantaneous phase and earth overcurrent, four step directional or undirectional delayed phase and earth overcurrent, thermal overload and two step underand overvoltage functions are examples of the available functions allowing the user to fulfill any application requirement. The IED can also be provided with a full control and interlocking functionality including co-operation with the synchronism check function to allow integration of the main or back-up control.
