Earthing Design Studies
design and Design verification
Earthing system design and analysis are fundamental to ensuring that earthing systems perform their intended functions. Key performance parameters such as earth potential rise, touch potential, and step potential must be thoroughly verified to safeguard compliance and safety.
Our team delivers optimized, site-specific designs for applications of any scale or complexity—from unit HV/LV substations and EHV transmission substations to multi-gigawatt renewable energy projects including PV farms and offshore wind farms.
With extensive expertise, proprietary data analysis techniques, and industry-recognized engineering software, we provide designs and verifications compliant with international standards, including ENA TS 41-24, BS 50522, and IEEE Std. 80.
Earthing Measurements
Soil structure plays a crucial role in earthing system design, with Soil Resistivity and Electrode Resistance measurements providing essential data to quantify its impact. Accurate interpretation of these measurements is vital to maintaining system integrity given its numerous external influencing factors.
Our specialists combine advanced electrical network modelling with expert analysis to identify and mitigate risks, ensuring earthing systems that are safe, reliable, and fully compliant with engineering and regulatory standards.
Electromagnetic Analyses
Electromagnetic Interference
Metallic services, including utility pipelines and railways systems, are vulnerable to electromagnetic interference (EMI) from the electrical network. These conditions pose health and safety hazards and asset integrity risks if not properly analysed and addressed.
Our specialists deliver detailed EMI analyses and design effective mitigation strategies to ensure system safety, reliability, and compliance.
Electromagnetic Fields
Electrical networks inherently generate electromagnetic fields (EMF), which may present health and safety risks. EMF can also create electromagnetic compatibility (EMC) issues, leading to equipment malfunctions and, in severe cases, wider network failures.
Axonas provides comprehensive EMF studies using state-of-the-art data-driven analytical techniques to support system design, occupational guidelines, and operational procedures.
Power System Design
Power System Analysis
Effective power system analysis is essential for ensuring the safe, reliable, and efficient operation of electrical networks. These analyses provide critical insights into system performance, stability, and resilience under a wide range of operating conditions, enabling informed decision-making throughout the design, development, and operational lifecycle.
At Axonas, we perform a comprehensive range of power system analyses, including:
Load Flow and Voltage Regulation – to evaluate system loading, voltage profiles, and power distribution efficiency.
Fault Level Analysis – to determine short-circuit currents and ensure equipment ratings and protection systems are appropriately coordinated.
Contingency Analysis – to assess system performance and stability under failure or outage scenarios.
Harmonic Analysis – to identify and mitigate power quality issues arising from non-linear loads and converter-based systems.
Insulation Coordination – to verify overvoltage protection and ensure insulation systems are properly specified and rated.
Our team combines deep technical expertise with advanced modelling tools and practical engineering experience to deliver accurate, actionable insights. We ensure every analysis supports the design of power systems that are safe, efficient, compliant, and optimised for long-term performance.
Lightning Protection Analysis
Transient Analysis
Transient analysis is critical in evaluating the response and withstand capability of integrated lightning protection systems when exposed to high-frequency events such as lightning strikes.
Outdoor substations, overhead lines, and transmission towers are particularly susceptible to direct lightning impacts. Without proper consideration of these risks during design, the consequences may include equipment damage, power outages, or even widespread blackouts.
Our team conducts comprehensive transient analyses to validate and optimize the integrity of lightning protection systems.
Lightning Shielding
Lightning shielding is a critical protection measure designed to safeguard structures and equipment from direct lightning strikes.
The consequences of a direct lightning strike can be severe, posing risks to safety, reliability, and operations. Conducting detailed lightning shielding design analysis is essential for mitigating these risks effectively.
Whether your project requires a new design, or the verification of an existing or proposed solution, our specialists can provide the required technical expertise to ensure reliable and compliant lightning shielding systems.
