- Redundancy Needs: Opt for dual-channel control in critical grids (e.g., islanded microgrids).
7. Precautions
-
Installation:
- Follow ABB’s wiring guidelines (separate power/signal cables to prevent EMI).
- Torque busbar connections to 10 N·m; ensure proper ventilation (200 mm clearance around the unit).
-
Commissioning:
- Calibrate voltage/current sensors using ABB’s UNITROL Commissioning Tool (UCT).
- Test fault protection (e.g., overvoltage/undercurrent) in simulated grid conditions.
-
Maintenance:
-
Inspect thyristor cooling fans quarterly; replace every 5 years.
-
Update firmware annually via ABB’s remote management platform.
