ABB FEEDER PROTECTION AND CONTROL REF620 ANSI NUMERICAL RELAY

Reliability, security, and dependability with Relion: REF620 ANSI Feeder protection relay is a dedicated feeder relay perfectly aligned for the protection, control, measurement and supervision of utility substations and industrial power systems.

REF620 is a member of ABB’s Relion family and a part of its 620 protection and control product series. The 620 series A are characterized by flexibility and performance for demanding utility distribution and industrial applications. Engineered from the ground up, the 620 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation devices.

Application
The REF620 provides main protection for overhead lines, cable feeders, and busbar systems of distribution substations. It can be applied for protection and control of grounded and ungrounded distribution systems. It offers support for single breaker, 1,5 breaker and double breaker feeder configurations. Flexible order coding allows for choosing configurations to best fit your distribution feeder application needs.

Scope

  • Feeder protection for overhead lines, cable feeders, and busbar systems of distribution substations.
