Abb 1mrk505137 Ben Line Differential Protection Ied - China

ABB 1MRK505137-BEN Line differential protection IED DESCRIPTION The RED 670 IED is used for the protection, control and monitoring of overhead lines and cables in all types of networks.

The IED can be used up to the highest voltage levels.

It is suitable for the protection of heavily loaded lines and multi-terminal lines where the requirement for tripping is one-, two-, and/or three pole.

The IED is also suitable for protection of cable feeders to generator block transformers.

FEATURES • A protection, control, and monitoring IED with extensive functional library and configuration possibilities and expandable hardware design to meet specific user requirements • For overhead lines and cables • For transformer feeders • For single and/or three phase tripping • High impedance differential protection for tee-feeders • Phase-segregated line differential protection with up to six stabilized inputs for up to five line terminals with: - Charging current compensation - Separate inputs for each CT in double breaker, ring and one and a half breaker installations for improved through fault stability - Suitable for multiplexed, route switched, as well as dedicated fibre, communication networks using C37.94 protocol - Power transformers can be included in the protected zone - Transfer of up to eight binary signals - Time synchronization with the echo-method or built-in GPS • Full scheme phase-to-phase and phase-to-earth distance protection with up to three zones: - All types of scheme communication - Load encroachment feature • Synchrocheck and dead-line check function for single- or multi-breaker arrangements: - Selectable energizing direction - Two functions with built-in voltage selection - For automatic or manual synchrocheck and with different settings • Auto-reclosing function for single- two-, and/or three-phase reclosing: - Two functions with priority circuits for multi-breaker arrangements - Co-operation with synchrocheck function - Can be switched On-Off from remote through communication or with local switches through binary inputs • Selectable additional software functions such as distance protection, control and monitoring • Built-in data communication modules for station bus IEC 61850-8-1 • Data communication modules for station bus IEC 60870-5-103, LON and SPA • Integrated disturbance and event recorder for up to 40 analog and 96 binary signals
