Arc Flash Study
Arc Flash Study for industrial facilities, utilities, renewable energy plants, data centers, and electrical infrastructure projects worldwide. Our engineers perform detailed Arc Flash Hazard Analysis in accordance with IEEE 1584-2018 and NFPA 70E standards to evaluate electrical safety risks and determine incident energy levels within power distribution systems. Arc Flash Study identifies potential arc flash hazards, calculates incident energy levels, determines arc flash boundaries, and defines required personal protective equipment (PPE) to ensure personnel safety and regulatory compliance.
Using advanced power system analysis software such as ETAP, DIgSILENT PowerFactory, and SKM Power Tools, we deliver accurate arc flash calculations and mitigation recommendations for low-voltage and medium-voltage electrical systems.
What is Arc Flash Study?
Arc Flash Study is an engineering assessment used to evaluate the energy released during an electrical arc fault in a power system. When an arc fault occurs, extremely high temperatures and pressure waves can be produced, causing severe equipment damage and life-threatening hazards to personnel.
The Arc Flash Study calculates:
• Incident Energy (cal/cm²)
• Arc Flash Boundary
• Personal Protective Equipment (PPE) requirements
• Arc Flash Labels for electrical equipment
The study helps organizations improve electrical safety, regulatory compliance, and system protection coordination.

Why Arc Flash Hazard Analysis is Required
Arc flash incidents are among the most dangerous electrical hazards in industrial facilities. International safety standards require electrical systems to be evaluated to protect workers and maintain safe operating conditions.
An Arc Flash Study is required to:
• Identify arc flash hazards in electrical systems
• Determine incident energy exposure levels
• Establish arc flash boundaries
• Define PPE requirements for personnel
• Improve electrical protection system coordination
• Ensure compliance with international electrical safety standards
Performing regular Arc Flash Studies helps reduce the risk of electrical accidents and improves overall system reliability.
Arc Flash Study Standards
Our Arc Flash Studies are performed according to internationally recognized standards including:
• IEEE 1584 – Guide for Performing Arc Flash Hazard Calculations
• NFPA 70E – Standard for Electrical Safety in the Workplace
• IEC 61482 – Protective Clothing Against Thermal Hazards of Electric Arc
• OSHA Electrical Safety Guidelines
These standards define the methodology for calculating arc flash incident energy and establishing safe working practices for electrical systems.
