Arc Flash Solutions
Arc Flash Solutions & Capabilities
At Mangan Power Group, we deliver turnkey arc flash solutions tailored for utility, industrial, and energy-sector clients operating high-power electrical systems. Our services combine decades of power systems experience with rigorous engineering standards to protect personnel, equipment, and operations from arc flash incidents. From hazard assessments and mitigation design to labeling, training, and system upgrades, we serve as your trusted engineering partner in reducing arc flash risks across the facility lifecycle.
We help clients navigate the increasingly complex requirements of NFPA 70E, IEEE 1584, OSHA 1910, the NESC AR APP guidelines, and corporate safety protocols, ensuring full compliance while optimizing power system performance. Whether for greenfield sites, retrofits, or audits, Mangan Power provides detailed insight and practical engineering strategies to help you identify, analyze, and eliminate arc flash hazards at their source.
Our Arc Flash Capabilities
Hazard Identification & Risk Assessment
- Perform detailed arc flash hazard studies based on IEEE 1584 and client-specific parameters
- Model worst-case incident energies and arc flash boundaries across Medium and Low Voltage systems.
- Evaluate fault currents, protective device settings, and coordination using state of the art analysis programs.
- Identify cascading fault conditions and devices contributing to excessive energy release.
- Calculate incident energy levels at each bus or equipment enclosure.
- Assign appropriate PPE categories and approach boundaries per NFPA 70E Annex D.
Engineering Design & Mitigation
- Design and implement solutions like zone-selective interlocking (ZSI), arc-resistant switchgear, or fast-tripping relays.
- Recommend equipment upgrades or retrofits that reduce arc duration and intensity.
- Re-engineer protective relay and breaker settings to minimize clearing time during faults.
- Validate settings through time-current coordination curves and device manufacturer guidelines.
- Engineer safe racking procedures using remote racking systems to reduce arc flash exposure.
- Design and integrate remote disconnect switches and maintenance bypass panels.
Field Implementation & Compliance
- Generate NFPA 70E-compliant arc flash labels for all energized equipment.
- Deliver one-line diagrams, study reports, breaker settings, and digital files for ongoing compliance.
- Ensure adherence to OSHA 1910 Subpart S, NFPA 70E Chapter 1, and NESC AR PPE through documented procedures and engineering controls.
- Support annual review requirements and assist during safety audits or inspections.
- Calculate incident energy levels at each bus or equipment enclosure.
- Assign appropriate PPE categories and approach boundaries per NFPA 70E Annex D.
Training, Oversight & Lifecycle Management
- Provide hands-on NFPA 70E training for electrical workers, operators, and maintenance staff.
- Offer customized PPE guidance, hazard awareness, and safety procedures.
- Assist with updating Electrical Safety Programs (ESPs), Lockout/Tagout (LOTO) procedures, and Energized Work Permits (EWPs).
- Monitor system changes to ensure updated arc flash documentation and labels.
- Provide engineering oversight during facility upgrades or equipment replacements affecting arc flash studies.
- Support continuous improvement efforts and long-term mitigation planning.
