This \u003cstrong\u003ebusbar protection IED\u003c\/strong\u003e provides selective, reliable, and fast fault clearance for all types of internal phase-to-phase and phase-to-earth faults in solidly earthed or low-impedance earthed power systems. It is also capable of handling internal multi-phase faults in isolated or high-impedance earthed power systems. Belonging to the Relion protection and control product family, the \u003cstrong\u003eABB REB670\u003c\/strong\u003e implements the core design requirements of the IEC 61850 standard to deliver fully
