An Arc Flash is an electrical discharge caused by a fault between live conductors-either through direct contact or via conductive paths-triggering a powerful and dangerous release of energy. In industrial environments, such incidents can lead to serious injuries, equipment damage, and operational downtime.
1. Safeguards personnel from severe burns, shock, or fatal injuries.
2. Helps prevent costly equipment damage, production losses, and liability issues.
3. Ensures compliance with international safety standards like OSHA, IEEE 1584, NFPA 70E, and NEC.
4. Highlights risk zones and appropriate PPE requirements.
At Tera Nexus, we offer a comprehensive Arc Flash Analysis service tailored for industrial and commercial facilities. Our services include:
Data Collection & Verification
On-site gathering of all relevant electrical infrastructure data, equipment specs and layouts. Verification, digitization, and quality checking to ensure accuracy.
Modelling & Engineering Studies
Using advanced simulation tools (e.g. ETAP, SKM, or client-preferred software) to build a model of your electrical network. Performing load flow, short-circuit, and protective device coordination studies.
Incident Energy & Boundary Calculations
Determining incident energy levels and arc-flash / shock boundaries so you know where safe approach distances lie.
PPE Categorization & Labeling
Based on our assessments, recommending and classifying required Personal Protective Equipment, then preparing Arc Flash labels and warnings for your electrical panels & enclosures.
Standards & Compliance Assurance
All our studies are conducted in strict accordance with OSHA standards, NFPA 70E, IEEE 1584 (latest edition), NEC, or other relevant regulatory frameworks.
Training & Risk Mitigation Guidance
We also provide training for your employees on Arc Flash hazards, safe work practices, and correct use of PPE. Plus, we recommend engineering or procedural changes to reduce risk exposure.
Tera Nexus is committed to making your electrical operations safer and compliant. Our goal is to:
1. Minimize Arc Flash risk through proactive engineering & safety measures.
2. Provide clarity and actionable insights to your operations team.
3. Reduce downtime and prevent accidents.
4. Keep your facility up to date with evolving safety norms and regulatory requirements.
1. What is an Arc Flash Study and why is it necessary?
An Arc Flash Study is a technical engineering analysis that determines the risk of electrical arc flash hazards in your facility. It is necessary to protect personnel from life-threatening injuries, ensure compliance with NFPA 70E and OSHA regulations, and prevent catastrophic equipment failure.
2. How often should an Arc Flash Study be updated?
According to NFPA 70E (Article 130.5), an arc flash risk assessment must be reviewed and updated at least every five years. However, you should update your study immediately if there are major changes to your electrical system, such as adding new transformers, changing protective device settings, or switching utility providers.
3. Which standards are used for the calculations?
Our engineering team utilizes the IEEE 1584 "Guide for Performing Arc-Flash Hazard Calculations" for all incident energy and boundary distance modeling. We also ensure all safety protocols and PPE requirements align with the latest NFPA 70E and NEC (National Electrical Code) standards.
