With the addition of a new form factor to support efficient replacement of legacy ANSI microprocessor protection relays, ABB has announced the completion of the ANSI Relion 650 series portfolio. This Relion portfolio makes it easier for utility personnel to benefit from a wide range of products for power systems protection, control, measurement and supervision.

The 3U form factor simplifies life-cycle management and provides utilities the opportunity for stepwise migration to advanced functionality and improved performance.

The Relion family delivers maximum flexibility and performance for generation, transmission and distribution. ABB’s portfolio of interoperable and future-proof solutions are designed to implement the core values of IEC 61850, enabling advanced substation automation applications for line, busbar, transformer and generator protection, as well as substation control.
