The REB670 IED (Intelligent Electronic Device) is engineered for the protection and monitoring of busbars, T-connections, and meshed corners across medium to extra high voltage levels, accommodating up to six zones. With its extensive I\/O capabilities, the REB670 is suitable for single, double, and triple busbar configurations, with or without transfer bus, double-circuit breaker, or one-and-a-half circuit breaker arrangements.<\/p>\n

The device ensures selective, reliable, and rapid fault clearance for all internal phase-to-phase and phase-to-earth faults in solidly earthed or low-impedance earthed power systems. It is also equipped to manage all internal multi-phase faults in isolated or high-impedance earthed power systems.<\/p>\n
