Earthing/Grounding Studies
Comprehensive earthing system design, analysis, and lightning protection in accordance with international standards
What are Earthing/Grounding Studies?
Earthing and grounding studies are critical for ensuring the safety and reliability of electrical installations. These studies involve the planning, calculation, and measurement of earthing systems to protect personnel, equipment, and structures from electrical hazards. Proper earthing design minimizes the risk of electric shock, ensures effective fault current dissipation, and maintains system stability during fault conditions.
Our comprehensive earthing studies are conducted in accordance with internationally recognized standards including EN 50522:2022, IEEE 80:2013, IEEE 81, BS 7430, and IEC 60479, ensuring compliance with safety regulations and best practices for diverse applications ranging from substations to renewable energy facilities.
