product description：
The REU615 voltage protection measurement and control device is well suited for voltage and frequency protection in public and industrial distribution systems, including grids with distributed generation. The REU615 IEC voltage protection measure and control unit is also ideal for voltage regulation.
The RREU615 voltage protection measurement and control device is available in two standard configurations: Standard A and Standard B.
Standard Configuration A can be used in applications such as bus low and overvoltage monitoring, load rejection (cut-off) and load recovery (reconnection). This configuration can also be used for over – and low-frequency protection of generators and other AC equipment, such as capacitor banks. In generator and motor protection applications, the REU615 also provides auxiliary protection by detecting frequency and voltage offsets. The integrated check synchronization function ensures a reliable connection between the equipment and the grid. In distribution networks with distributed generation, the REU615 also acts as a lem-loss-of-mains protection for a single generation unit.
Standard Configuration B can be used for manual or automatic voltage regulation with electric on-load regulator switch transformers. In small substations with only one transformer, the REU615 can be used for load side voltage regulation. Standard configuration B also has protection.
The REU615 IEC Voltage Protection measurement and Control unit is a member of the 615 product family in ABB’s Relion® product family.
