The Challenge
Large solar developments bring together extensive outdoor electrical infrastructure, including inverter stations and sensitive equipment. The lightning protection solution needed to address:
- Direct lightning protection for critical infrastructure
- Protection by isolation for inverter stations
- A site-specific design in accordance with IEEE Std 998
- A dedicated, insulated path for lightning current to earth
- Strike recording to support ongoing inspection and maintenance
- Coordination of design, equipment supply and final commissioning.
The Solution
LPINZ delivered a coordinated solution combining Leader Inception Theory design, Guardian Plus corona-minimising air terminals, HVSC Plus insulated downconductors and Bluetooth-enabled lightning strike recording.
The approach included:
- LIT design in accordance with IEEE Std 998
- Guardian Plus corona-minimising technology
- Protection by isolation for inverter stations: HVSC Plus (HVSC+) insulated downconductors withstand rating of at least 500 kV
- Bluetooth-enabled strike recording
- Full turnkey solution with LP, earthing and commissioning
