for maximum reliability of your power system
The RED 670 IED (Intelligent Electronic Device) is designed for protection, monitoring and control of overhead lines and cables. In addition, this IED is capable of handling transformer feeders, generator and transformer blocks. It provides an extensive functionality with configuration opportunities and expandable hardware to meet your specific requirements.
The RED 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 RED 670 IEDs with optional protection and control functions. For instance, in case of communication failures the optional full scheme distance protection ensures fault clearance. The wide application flexibility makes these IEDs an excellent choice for both new and retrofit installations.
The RED 670 IEDs feature phase-segregated current differential protection with excellent sensitivity for high resistive faults and secure phase selection for up to five line terminals. Two- or three-winding power transformers can be included in the protected zone. The line differential protection function handles all transformer vector groups and matches all transformer configurations with a simple parameter setting. This enables easy engineering since no extra CTs and protection equipment are needed. Advanced stabilization methods are used for detection of inrush current at transformer energization to ensure sensitive differential protection also when the power transformer is included in the protected zone.
The powerful RED 670 features full control and interlocking functionality required for control of apparatuses in a substation. The integrated HMI provides secure and quick local control and back-up control for substation automation systems.
RED 670 features extensive functionality and expandable I/O, which enables applications with multiple algorithms, multiple objects, integrated and distributed architectures. Thus, RED 670 provides efficient substation automation solutions in terms of performance, redundancy and cost for any high voltage application.
