Earthing Systems
Well designed and functioning earthing is essential in a power system, giving predictable fault currents, transient overvoltages and safe step and touch voltages for the general public.
Earthing Design
- Earthing system design and optimisation
- Earthing studies and simulations using XGSLab
- Fault current and earth potential calculations
- Inductive coordination and mitigation studies
- Lightning protection design and assessment
Field Testing
- Step and touch voltage assessments and measurements
- Earth electrode resistance and soil resistivity measurements
- Development and validation of novel measurement methods [1]
