Arc Flash Studies
Evaluate electrical systems to determine arc flash hazards and define appropriate safety boundaries and PPE requirements.
Service Overview
At Engineering Design Services, our Arc Flash Study services help clients understand and reduce the risks associated with energized electrical systems. We take an engineering-driven approach to evaluating electrical distribution systems, identifying potential arc flash hazards, and developing safer operating conditions for personnel and equipment.
Our team works closely with clients to analyze system configurations, fault currents, and protective device coordination to determine incident energy levels and required personal protective equipment (PPE). From new facility design to existing system assessments and compliance updates, we ensure studies are accurate, practical, and aligned with current safety standards.
By integrating power system analysis, field verification, and code compliance, we deliver arc flash studies that support safer maintenance practices, improved system reliability, and reduced operational risk.
Whether supporting plant expansions, system upgrades, or OSHA and NFPA compliance requirements, our team delivers arc flash solutions built for safety, accuracy, and long-term reliability.
