ABB REB611HBAABB1NN11G Busbar Protection Relay Unit

Feature & Principle

This protection IED adopts high impedance differential principle, monitors busbar current from each incoming and outgoing feeder. It identifies busbar internal short-circuit fault and trips rapidly to isolate fault section. It supports IEC61850 and GOOSE communication, built-in fault recorder, trip circuit supervision and self-diagnosis function.
