Electrical Earthing

Risk Assessment Surveys and measurements for substation or generation schemes on your electrical earthing system, voltages from 1kV to 765kV are undertaken by our highly qualified engineers.

Soil Resistivity

Soil resistivity testing is not only a key component to a successful electrical earthing system design, but is crucial in 'right-sizing' your design so that the earth is matched to the soil in which it's going to be installed.

More

EMI Studies

Fault current distribution, earth potential rise mapping, AC interference studies, and using industry standard CDEGS software, create your field assessment reports to meet the latest regulatory obligations.

More

Lightning Safety

Risk assessments undertaken to ensure lightning protection and electrical earthing systems can be safely integrated. High Frequency software is used to model the effects of a lightning stroke to structure, equipment, tank or substation.

GreyMatters takes "Electrical Earthing System Design" what is traditionally a "black art" and through measurement, analysis, constructional simulation software (CDEGS) and a lot of "grey matter"... translates electrical earthing system design issues into simple to understand visual images and risk maps, identifying where the risks really lie. GreyMatters designs technically secure safety electrical earthing solutions (grounding systems) for voltages between 1kV - 765kV in order to meet the recently updated international standards and regulatory obligations.

WHAT WE CAN DO FOR YOU?

Electrical Earthing System Design and Simulations - Electrical Earthing Design Risk Assessment Surveys and measurements for substation or generation schemes on voltages from 1kV to 765kV are undertaken by our highly qualified engineers.

Soil Resistivity Testing - Understanding the soil resistivity and its impact on Electrical Earthing System Design return current behaviour under fault conditions as part of the Safety Calculation requirements. Soil Resistivity Testing is not only a key component to a successful Electrical Earthing System Design, but it is crucial in 'right-sizing' your design so that the Electrical Earthing System is matched to the soil resistivity in which it's going to be installed.

HV Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) Studies - Our engineers assess fault current distribution, undertake earth potential rise studies & mapping, AC interference studies, and using the latest industry accepted CDEGS software create, your field assessment study reports so that your project meets all the latest regulatory obligations. EMC is the control of EMI so that unwanted effects are prevented.

Lightning Safety Studies - Risk assessment and design undertaken to ensure both the lightning protection and electrical earthing systems can be safely integrated. We use specialist High Frequency CDEGS software which allows us to model the effects of a lightning strike to a structure, piece of equipment, tank or substation.
