REC650 is used to control, protect and monitor different types of intervals in the power grid. The IED is particularly suitable for control systems with distributed control devices where high reliability intervals are required. It is mainly used by secondary transmission substations. It is suitable for the control of all primary equipment under single bus single CB and double bus single CB switchgear arrangement.
This control can be implemented from afar (SCADA/Station) via a communication bus or at a local human-machine interface. Different control configurations can be used, and one control device is recommended for each interval. Interlocking modules can be used for all common types of switchgear arrangements. This control function gives the highest possible safety based on the principle of selection before operation. A synchronous control function can be used for interlocking of circuit breaker closing. It can also provide the synchronization function of the circuit breaker to close correctly in the asynchronous network.
