Power System Studies and Arc Flash Analysis
Comprehensive electrical studies to ensure system reliability, safety, and compliance with NFPA 70E and IEEE standards.
At APT Testing, we specialize in Power System Studies and Arc Flash Analysis that go beyond compliance—they’re engineered for performance, protection, and peace of mind. Whether you’re designing a new facility or auditing an existing one, our studies provide the insights needed to optimize system behavior, reduce risk, and meet the latest industry standards.
Using advanced tools like ETAP and SKM Power Tools, our engineers model real-world electrical conditions to simulate faults, evaluate protective device coordination, and calculate arc flash boundaries. Every study is conducted in accordance with NETA ATS, NFPA 70E, IEEE 1584, and NEC 230.95—ensuring your system is not only compliant, but safe and resilient.
Scope of Services
🔹 Short Circuit & Protective Device Coordination Studies
We analyze fault currents and evaluate protective device settings to ensure proper isolation, minimize downtime, and prevent equipment damage.
🔹 Arc Flash Hazard Analysis & Labeling (NFPA 70E)
Our team calculates incident energy levels and defines PPE categories, producing compliant arc flash labels and boundary maps to protect personnel.
🔹 Load Flow & Voltage Drop Analysis
We simulate real-time load conditions to identify bottlenecks, voltage imbalances, and inefficiencies—ensuring stable power delivery across the system.
🔹 Motor Starting & Harmonic Studies
We evaluate motor behavior under various load conditions and assess harmonic distortion to prevent nuisance tripping and equipment degradation.
🔹 Ground Fault Protection Evaluation (NEC 230.95)
We verify ground fault protection schemes for service equipment, ensuring safe operation and compliance with NEC requirements.
🔹 Equipment Evaluation for Adequate AIC Ratings
We confirm that all breakers, fuses, and switchgear are rated to withstand available fault currents—preventing catastrophic failure.
🔹 Relay Setting & Coordination Optimization
We fine-tune relay settings to ensure selective coordination, fast fault clearing, and system stability under abnormal conditions.
Why It Matters
Electrical systems are dynamic—and so are the risks. Without proper studies, even well-designed systems can fail under stress. Our power system studies provide the data and clarity needed to make informed decisions, protect assets, and safeguard lives.
At APT Testing, we don’t just run simulations—we engineer certainty.
