Earthing Design, Lightning Protection and EMFI Analysis

Soil Resistivity Measurement and Analysis:

• Understanding soil's electrical properties is the foundation of effective earthing system design.
• We employ advanced techniques such as the Wenner and Schlumberger methods for precise resistivity data collection.
• Using uniform, multilayer, and multizone soil models, we ensure accurate analysis for optimized designs in diverse terrains.

Fault Current Distribution Analysis:

• Identifying high-current zones and their impact is critical for safe earthing system design.
• Our studies analyze fault current pathways, ensuring the safe dissipation of energy to protect equipment and personnel.

New Earth Grid Design:

• Custom-designed earth grids tailored to site-specific requirements and operational demands.
• Fully compliant with Australian standards (AS/NZS 3000, AS 1768) and international benchmarks (IEC 61936-1, IEEE 80).

Existing Earthing System Verification and Modification:

• Assessing and optimizing the performance of existing earthing systems using advanced modeling tools like XGSLab.
• Recommendations for upgrades to improve compliance, safety, and operational resilience.

Earth Potential Rise (EPR), Touch Voltage, and Step Voltage Calculations:

• Comprehensive calculations ensure safety during faults by mitigating risks posed by voltage gradients.
• Systems are designed per standards such as AS 2067, IEEE 80, and IEC 60364.

Earth Grid Testing:

Verification of installed earth grids is crucial for maintaining safety and functionality. We perform on-site tests such as:

• Fall of Potential Method: Measures earth grid resistance and ensures compliance with AS/NZS 3000 and IEEE 81.
• Current Injection Test Method: Used to validate the performance of large-scale or complex earth grids in alignment with IEC and IEEE standards.

Lightning Protection System Design:

• Custom-designed systems to mitigate lightning strike risks, including air terminals, down conductors, and earth terminations.
• Fully compliant with AS 1768, IEC 62305, and NFPA 780 standards, ensuring the highest level of protection for your assets.

Electromagnetic Interference (EMI) Mitigation:

• Specialized strategies to prevent unwanted EMI from affecting sensitive equipment and systems.
• Solutions include shielding, filtering, and grounding techniques designed to international EMC standards (IEC 61000 series).

Cathodic Protection Design:

• Long-term protection of metal structures, such as pipelines and storage tanks, against corrosion.
• Tailored solutions for both sacrificial anode and impressed current systems to meet ISO 15589 and NACE standards.

Training and Workshops:

• Empowering your team with up-to-date knowledge and best practices in earthing, EMI mitigation, and lightning protection.
• Tailored sessions for engineers, technicians, and management to stay ahead in industry advancements.
