Power System Studies
Our power system studies ensure electrical network reliability and grid compliance through comprehensive analysis using industry-leading software. We identify potential issues, optimise performance, and provide professionally indemnified reports that facilitate grid connection agreements. Our studies cover load flow, harmonic analysis, and protection coordination to ensure safe, efficient operation.
Renewable Energy Consultancy
We provide specialist consultancy for large energy users transitioning to renewable energy systems. Our services include carbon audits, grid connection studies, and custom renewable energy system design incorporating solar, wind, and energy storage technologies. We ensure compliance with grid codes while optimising system efficiency and return on investment.
Harmonic Filters
Our harmonic filter solutions mitigate electrical disturbances caused by variable speed drives and inverters. We design passive and active filter systems that reduce equipment stress, prevent nuisance tripping, and ensure compliance with standards like IEC 61000 and IEEE 519. This maintains power quality and protects critical electrical infrastructure.
Point-on-Wave Switching
Our SynchroTeq-based point-on-wave switching technology eliminates inrush currents during transformer and capacitor energisation. This patented solution reduces mechanical stress, prevents voltage dips, and ensures compliance with Engineering Recommendation P28. It's particularly effective for renewable energy grid connections and industrial applications.
Earthing Systems
We design comprehensive earthing systems that ensure electrical safety and equipment protection. Our studies assess earth potential rise, evaluate soil resistivity, and ensure compliance with safety standards. This protects personnel, prevents equipment damage, and maintains system stability during fault conditions.
