The ABB REL670 manual provides operating instructions, configuration guidance, and technical parameters for the line distance protection and control unit.
The manual describes the REL670 as an intelligent electronic device that combines protection, control, and monitoring functions for overhead and cable lines. It details the extensive protection features such as distance, differential, over‑current, directional power, frequency and loss‑step protection, as well as control functions like automatic reclosing and synchronization.
It also covers hardware modules (power, I/O, mA, CT/PT, fiber‑Ethernet, GPS, IRIG‑B), communication options (IEC 61850‑8‑1, IEC 61850‑5‑103, TCP/IP, EIA‑485, DNP 3.0, LON, SPA, C37.94, G703/G703E1), installation wiring, configuration examples, and technical parameters for current, voltage, frequency and power consumption. This manual is written in Chinese.
