High Voltage Projects
Intercontinental Hotel
Client: Intercontinental Hotel, SA (via Lai Industries)
Year: 2025
Power Edge Engineering designed, tested and commissioned an 11 kV automatic transfer scheme for new Schneider Electric high-voltage switchgear. Following comprehensive FAT and SAT validation, the system was successfully deployed during a planned outage and operated as intended on first commissioning. The scheme provides high-reliability redundant power, automatically transferring to an alternate feeder within 250 milliseconds of a loss of mains event, ensuring continuity of supply for critical operations.
Power Water
Client: PowerWater, NT (via McMahon Services)
Year: 2026
Power Edge developed and validated the SEL protection relay settings for the Darwin River Dam Expansion Project. The solution incorporated advanced protection logic, coordinated timing schemes, inter-trips, blocking functions and local/remote operational controls to support reliable high-voltage power station protection. Extensive off-site testing confirmed full operational performance prior to installation, reducing commissioning time and lowering on-site project costs
Clean Peak Energy
Client: Clean Peak Energy, SA
Year: 2026
As the Tonsley Innovation District continues its rapid transformation, Power Edge was selected to support the integration of a major new commercial development into the district's evolving embedded HV network. Through comprehensive LV and HV protection coordination and grading studies, our team optimised system selectivity and fault response, ensuring reliable operation while enabling the network to scale efficiently with future growth.
VUDA Power Station
Client: VUDA Power Station, Fiji (via Infracon)
Year: 2026
Power Edge Engineering delivered an advanced arc-flash protection solution for the VUDA Power Station's ABB 11 kV switchgear, incorporating high-speed VAMP protection relays and ultra-fast arc detection technology. By dramatically reducing fault clearing times and limiting fault energy, the system enhances safety, protects critical power infrastructure and reduces the risk of costly generator and transformer damage. The result is a safer, more resilient power station with improved operational continuity.
