Main features and advantages:

Selecting the ABB REC670 1MRK002814-AB delivers significant operational advantages to power distribution systems. Its high-speed processing capabilities enable fault detection and isolation within 10-20 milliseconds, minimizing fault duration and reducing equipment damage during network disturbances. Unlike traditional protection relays with fixed functionality, this IED offers configurable protection schemes, allowing engineers to tailor settings to specific network requirements—from radial distribution feeders to complex meshed networks.

The device’s ruggedized design, including reinforced isolation and surge withstand capabilities, ensures reliable operation in the harsh electromagnetic environments typical of high-voltage substations. Its compliance with IEC 61850, the global standard for substation automation, simplifies integration with smart grid initiatives and enables interoperability with multi-vendor systems, reducing lifecycle costs. For maintenance teams, the advanced diagnostic features provide detailed event records, waveform captures, and self-monitoring capabilities, enabling faster post-fault analysis and reducing mean time to repair. Additionally, its support for remote configuration eliminates the need for on-site visits for routine setting changes, improving operational efficiency.

Installation and maintenance:

Before installing the ABB REC670 1MRK002814-AB, verify that the auxiliary power supply matches the device’s requirements (110/220 V DC or 100/240 V AC) and that it provides stable operation during voltage fluctuations. Ensure CT and VT connections are correctly sized and wired according to polarity requirements to prevent protection misoperation. Check network infrastructure compatibility for IEC 61850 communication, ensuring proper switch configuration and sufficient bandwidth for GOOSE messages and sampled values. Confirm the mounting location provides adequate cooling, with at least 50 mm clearance around the device, and that environmental conditions remain within the -40 to 70 °C operating range.

For ongoing maintenance, establish a quarterly review schedule of protection logs and event records to identify emerging issues or configuration discrepancies. Perform annual verification of protection settings against current network requirements, updating as needed through the IEC 61850 configuration tool. Inspect physical connections annually, ensuring terminal blocks remain tight and free from corrosion, particularly in humid environments. Keep firmware updated through ABB’s secure portal, applying updates during planned outages to avoid disrupting protection functionality.
