Earthing System Design & Testing
Safe, compliant and precisely engineered earthing solutions for utilities, substations, and industrial facilities.
Why a Robust Earthing System Matters
A well-designed earthing system is the foundation of electrical safety. It protects personnel, equipment, and infrastructure from dangerous fault currents and hazardous step and touch potentials.
Our engineers use advanced simulation software — including CDEGS — to model, validate and optimise earthing designs to Australian and international standards.
Soil Reactivity Test
On-site soil resistivity testing using the Wenner 4-pin method to determine soil layering and electrical characteristics for accurate earth grid design.
Earth Grid Design
Engineered earth grid designs using CDEGS simulation software, optimised for fault current dissipation and step/touch voltage compliance.
Earth Grid Compliance Check
Independent audit and verification of existing earthing systems against current Australian standards and network regulatory requirements.
Fault Finding
Systematic field testing and diagnostics to identify earthing faults, continuity breaks, and corrosion issues in existing installations.
How GridServe Supports Your Projects
GridServe provides comprehensive earthing system design and testing solutions across Australia for water, power, and gas utilities, renewable energy projects, asset relocation works, mines, government agencies, and private sector clients. Our team is committed to delivering every project safely, on schedule, and within budget.
Our Key Services
Earthing system design for HV substations, renewable energy facilities, BESS, and utility networks using advanced modeling software.
Electrical hazard assessments, including Earth Potential Rise (EPR) and Low-Frequency Induction (LFI) studies, along with pipeline mitigation strategies.
On-site testing and commissioning performed in line with industry standards and regulatory requirements.
Earthing System Design
We provide specialized earthing solutions for all voltage levels, from 11kV to 500kV, for utilities, generation, and renewable energy projects. Using CDEGS software, we deliver tailored and efficient designs that meet safety and compliance standards.
LFI, EPR, and EMF Assessments
GridServe has expertise in performing EPR and LFI studies, especially for water and gas utilities. Our team can design and implement mitigation measures in-house to minimize hazardous voltages on pipelines and protect assets from corrosion.
