Protection & Arc Flash Analysis

Designing electrical systems with safety and reliability in mind begins with effective fault detection and isolation. Our Protection & Arc Flash Analysis ensures that electrical faults are managed swiftly and selectively—minimizing equipment damage, operational disruption, and risk to personnel.

  • Protection Relay Coordination

Optimized coordination of protective relays ensures only the faulted part of the network is isolated, preserving uptime and preventing cascading outages.

  • Arc Flash Hazard Analysis

Accurate incident energy calculations define arc flash boundaries, recommend appropriate PPE, and improve workplace safety through detailed labeling and compliance.

  • Fault Clearing Time Evaluation

Assessing breaker and relay response times helps limit arc flash energy exposure and enhances overall protection system performance.

  • Device Duty Assessment

Verifies that fuses and circuit breakers are rated correctly to safely interrupt potential fault currents, avoiding catastrophic equipment failure.

What is the purpose of arc flash analysis ?

Arc flash analysis helps define safe working distances, determine proper protective gear, and ensure compliance with NFPA 70E and IEEE 1584 standards—all to reduce injury risk during electrical incidents.

Why is relay coordination critical ?

Properly coordinated relays isolate only the affected circuit during a fault. This prevents unnecessary outages, protects equipment, and enhances the resilience of the entire system.
