The REC670 is designed for controlling, protecting, and monitoring various bay types within power networks. It excels in systems with distributed control IEDs across bays, prioritizing reliability, and can operate at high voltage levels. It effectively manages apparatuses in diverse switchgear arrangements.
Control can be executed remotely via SCADA/Station or locally through HMI. Various control configurations are available, allowing either one control IED per bay or shared usage across multiple bays. Interlocking modules cater to common switchgear arrangements, ensuring secure operations through the select-before-execute principle.
Synchronism Control and Protection
Synchronism control features enable interlocking of breaker closing, ensuring proper synchronization in both synchronous and asynchronous networks. Protection functions are versatile, accommodating different station types and busbar arrangements. Auto-reclose functionalities, including priority circuits for multi-breaker setups, enhance system resilience. Breaker failure functions ensure continued operation even in the event of a failure.
Protection Functions
The REC670 offers a range of protection functions, including high set instantaneous phase and ground overcurrent, directional or non-directional delayed phase and ground overcurrent, thermal overload, and under- and overvoltage functions. These functions can be tailored to meet specific application requirements.
Multi-Feeder Protection and Control
Equipped with six overcurrent, ground fault, autorecloser, and measuring functions, the REC670, along with its multi-display local HMI, serves as a versatile multi-feeder protection and controller for distribution buses.
Communication and Logic
Dual-directional channels facilitate intertrip and binary signal transfer between IEDs within the station or neighboring stations. Advanced logic capabilities, configured through a graphical tool, enable specialized applications such as automatic opening of disconnectors, breaker ring closure, and load transfer logics. The graphical configuration tool streamlines testing and commissioning processes.
Disturbance Recording and Fault Locator
Disturbance recording and fault locator features allow independent post-fault analysis, aiding in identifying primary disturbances and single failures within the protection system.
