Engineering-Grade Arc Flash Analysis, Arc Flash Calculation & Hazard Assessment for Industrial & Utility Power Systems
ENABLING ELECTRICAL SAFETY AND ARC FLASH RISK MITIGATION THROUGH ADVANCED ARC FLASH STUDIES
An Arc Flash Study (also known as Arc Flash Analysis or Arc Flash Hazard Analysis) evaluates electrical power systems to identify arc flash risks, perform incident energy calculations, and define safe working boundaries.
This critical electrical safety study supports accurate PPE selection, arc flash labeling, and safer maintenance practices. It enhances workplace safety, ensures regulatory compliance with standards such as IEEE 1584 and NFPA 70E, and improves power system reliability by optimising protection settings and reducing arc flash risk across industrial and utility networks.
Purpose of Arc Flash Study
System Data Validation
Verification of SLD, equipment ratings, and protection device data prior to modelling.
Short Circuit Analysis Input
Fault current calculation as the basis for arc flash evaluation.
Protection Device Modelling
Incorporation of relay settings, fuse curves, and breaker characteristics.
Incident Energy Analysis
Calculation of arc flash energy levels across all buses and equipment.
Arc Flash Boundary Calculation
Determination of safe approach distances for each location.
PPE Category Determination
Assignment of PPE levels based on calculated incident energy.
