RET630 is a comprehensive transformer management IED for protection, control, measuring and supervision of power transformers, unit and step-up transformers including power generator-transformer blocks in utility and industry power distribution networks. RET630 is a member of ABB’s Relion®
product family and a part of its 630 product series characterized by functional scalability and flexible configurability. It also features necessary control functions constituting an ideal solution for transformer bay control.
RET630 provides main protection for two-winding power transformers and power generator-transformer blocks. Two pre-defined configurations to match your typical transformer protection and control specifications are available. The configurations can be used as such or easily adapted or extended with freely selectable functions, by means of which the IED can be fine-tuned to exactly satisfy the specific requirements of your present application.
RET630 incorporates local and remote control functions. The IED offers freely assignable binary inputs/outputs and logic circuits for establishing bay control and interlocking functions for circuit breakers and motor operated switch-disconnectors. RET630 supports both single and double busbar substation layouts.
