for maximum reliability of your power system
The REL 670 IED (Intelligent Electronic Device) is designed for protection, monitoring and control of overhead lines and cables. It provides an extensive functionality with configuration opportunities and expandable hardware to meet your specific requirements. This powerful IED provides distance protection for a complete double circuit, parallel operating line.
REL 670 features full scheme distance protection with independent phase selection, power swing detection and a wide range of scheme communication logics. Furthermore, REL 670 allows you to protect and control several objects, for instance a line and a transformer with one single IED.
The REL 670 IEDs are delivered pre-configured, type tested and set with default parameters for fast and efficient commissioning. These IEDs are equipped with complete functionality adapted for four different configuration alternatives: single pole breaker or multi-breaker arrangement with single or three phase tripping. If needed, they can also be easily adapted to meet the specific requirements of your power system. Furthermore you can increase the functionality of your REL 670 IEDs with optional protection and control functions. The wide application flexibility makes these IEDs an excellent choice for both new and retrofit installations.
REL 670 provides protection of power lines with high sensitivity and low requirement on remote end communication. Measurements and setting of all five zones with six setting groups are made completely independently, which ensures high reliability for all types of lines. The distance and earth-fault protection functions can communicate with remote end in any communication scheme. It offers full control and interlocking functionality required for control of apparatuses in a substation. The integrated HMI allows secure and quick local control for stand-alone applications and provides back-up control for substation automation systems.
REL 670 features extensive functionality and expandable I/O, which enables applications with multiple algorithms, multiple objects, integrated and distributed architectures. Thus, REL 670 provides efficient substation automation solutions in terms of performance, redundancy and cost for any high voltage application.
