Installation and maintenance:

Before installing the REF615C_C HCFFAEAGANB2BAN1XC, verify control power compatibility and ensure proper isolation from high-voltage components. Check that current and voltage transformer ratios match the relay’s input ranges to ensure measurement accuracy. For digital substations, confirm IEC 61850 configuration consistency with other IEDs and SCADA systems.

For ongoing maintenance, schedule annual verification of protection settings using certified test equipment to ensure compliance with network requirements. Inspect communication connections quarterly for tightness and corrosion, especially in humid environments. Utilize the relay’s event log and oscillography features to analyze fault events, which helps optimize protection coordination over time. Always backup configuration files before performing firmware updates, and ensure updates are compatible with existing system architecture.
