For optimized control and reliable operation of your switchyard
REC650 – your best choice for sub-transmission applications
REC650 offers optimum ‘off-the-shelf’ solutions for control applications in single breaker applications in single and double busbar arrangements. For double busbar arrangements, control of a bus coupler bay is also available. The type tested variants are equipped and configured with complete functionality, and with default parameters for easy handling of products – from ordering, engineering and commissioning to reliable operation.
The 650 series IEDs (Intelligent Electronic Device) introduce a number of innovations, such as significantly reduced parameter setting. In the 650 series IEDs, all basic parameters are set before delivery from the factory. You only need to set the parameters specific to your application, such as line data. This allows the IEDs to be quickly taken into operation.
You can control and visualize locally up to eight primary apparatus in a bay with REC650. The control is based on the select before operate principle, which ensures secure operation and helps avoid human error. By selecting the control screen as a default screen in REC650, you can quickly execute control commands, and see the most important values. There are three pages of alarm indications and each page consists of 15 dynamic three-colour indication LEDs. These three-colour LEDs can present the status of any binary input signal on the HMI of REC650 IEDs.
The advanced interlocking functionality of REC650 allows you to avoid dangerous or damaging switchgear operations and to assure personnel safety. The IED perform secure bay- and station wide interlocking using easy-to-use reservation functionality. Reservation prevents simultaneous operation of apparatus and ensures that the interlocking information is correct at the time of operation.
Ready-made and tested interlocking modules are available for almost any type of switchgear arrangement. The REC650 IED utilize GOOSE messaging based on the IEC 61850 standard to perform horizontal communication and interlocking. This provides a cost-efficient solution for the interlocking.
In addition to interlocking, the output relays of the REC650 IED feature an integrated continuous supervision function to ensure high security against unwanted operation. Meeting the stringent EMC requirements set for protection relays, REC650 provide secure control of your primary equipment.
The REC650 features extensive circuit breaker condition monitoring and monitoring of the station battery supply. The three trip circuit supervision outputs of the IED eliminate the need for an external trip circuit supervision unit.
Both REC650 and REC670 bay control IEDs are designed for the control, monitoring and protection of circuit breakers, disconnectors, and earthing switches in different switchgear configurations. Providing extensive application opportunities, both these IEDs are designed for IEC 61850. They implement the core values of this standard, which ensures open, futureproof and flexible system architectures, with state-of-the-art performance. The IEDs are therefore ideal for refurbishment and extension of existing installations as well as for new installations.
