6. Selection Recommendations
- Compatibility: Ensure compatibility with your substation automation protocol (e.g., IEC 61850 for smart grids).
- Environment: Choose IP54 rating for outdoor installations; verify temperature and humidity ranges.
- Functionality: Prioritize required protection functions (e.g., distance protection for transmission lines vs. overcurrent for feeders).
- Budget: Balance features with cost—modular design allows phased upgrades (e.g., add communication modules later).
7. Precautions
- Installation: Follow ABB’s wiring guidelines to avoid EMI interference; ensure proper grounding.
- Maintenance: Schedule annual firmware updates and functional tests (via ABB’s Relion Manager software).
- Safety: Disconnect power before servicing; adhere to IEC 61850-5 safety standards for live network operations.
- Storage: Store in dry environments (≤60% humidity) at temperatures between -40°C and +85°C.
