Longer life and cost efficiency for your installations
Breaker protection REQ650 provides a standalone solution for applications where the integration of the breaker failure protection or automatic reclosing function into the main line protection IED (Intelligent Electronic Device) is not preferred or suitable. This IED also offers local back-up protection, synchronizing, synchrocheck and energizing check functionality to enable well-structured and reliable protection for various applications.
REQ650 provides you with an ideal protection and control solution for circuit breaker connected objects. The breaker failure protection allows for high speed back-up tripping of surrounding breakers, and re-tripping of the own breaker in any single breaker busbar arrangement, for instance to avoid operational mistakes during testing. This function is essential in substations that require local back-up protection. Breaker protection REQ650 is also the perfect choice for refurbishment projects where old protection relays need to be replaced.
REQ650 – ease of use from ready-to-use solutions
REQ650 offers optimum ‘off-the-shelf’, ready-made application solutions for the protection and control of circuit breaker connected objects. The type-tested variants are delivered equipped and onfigured with complete protection functionality, and with default parameters for easy handling of products – from ordering, engineering and commissioning to reliable operation.
The 650 series IEDs introduce a number of innovations, such as a significantly reduced number of parameter settings and extended IED HMI functionality including 15 dynamic three color-indication LEDs per page, on up to three pages, and configurable push-button shortcuts for different actions. In the 650 series IEDs, most of the basic parameters are set before delivery from the factory. You only need to set the parameters specific to your application. The parameters related to the protected object are set as primary values, which significantly reduces the need to recalculate the current and voltage values. This allows the IEDs to be quickly taken into operation. The application manual includes setting examples to support the protection engineer.
