single phase and up to 8x3 CTs for REB670 three phase version) which can be connected to the differential IED. If the CT saturation has to be checked and preventive measures taken for every HV CT connected to the protection zone on one- by-one basis, the differential relay algorithm would be slow and quite complex.
State-of-the-art protection - for your equipment and your people. The REB670 IED (Intelligent Electronic Device) is designed for the protection and monitoring of busbars, T-connections and meshed corners from medium to extra high voltage levels in up to six zones. Due to its extensive I/O capability, REB670 protects single,
Relion® 670 series. Busbar protection REB670. Operator's manual The data, examples and diagrams in this manual are included solely for the concept or product description and are not to be deemed as a statement of A term used to describe how the relay behaves during a fault condition. For example a distance
overvoltage relay or power transformer neutral point overcurrent relay). Please refer to the technical reference manual for more details about the working principles of the differential function algorithm. 6.1.3.3. Check zone protection. M12474-3 v4. An integrated overall differential zone, so-called check zone, is available for.
REB670 IED fits both solutions. A simplified bus differential protection for multi-phase faults and earth faults can be obtained by using a single, one-phase. REB670 IED with delta VT overvoltage relay or external power transformer neutral associated error has been corrected a manual reset must be given to the IED.

ABB. Scheme Layout for
single pole operated circuit breakers and/or main and backup trip coils), a separate trip repeat relay unit is applied for the tripping of the circuit breakers in the station. In that case the tripping arrangement can be done in different ways. Section 6. 1MRK 505 302-UUS -. Differential protection. 122. Application Manual

Technical manual be responsible or liable for any loss or damage resulting from the use of this manual or the application of the equipment. every HV CT connected to the protection zone on one-by-one basis, the differential relay algorithm would be slow and
compared to other numerical differential protection devices. In-depth busbar protection knowledge. The REB670 IED continues ABB's strong track record in busbar protection, starting from analog busbar protection relays INX2/5,. RADSS, REB 101/103. So far, these relays have been success- fully installed for over 40 years.
Differential protection zones in REB 670 include a sensitive tion relays per zone of protection. REB 670 IED fits both solutions. A simplified bus differential protection for multi-phase faults and earth faults can be obtained by using a single, . case the manual reset is needed in order to reset the individual bay trip output
