Comprehensive Power System Studies
Done Accurately and Efficiently through Sound Engineering PrinciplesShort circuit, coordination, and arc flash analyses that balance equipment protection, worker safety, and fault isolation.
Engineering Studies for New and Existing Facilities
Services include short circuit analysis, protective device coordination, and arc flash hazard analysis. Additional study needs can be specified through the Request a Quote form or by contacting us.
Short Circuit Analysis
Short circuit analysis determines the available fault current throughout the electrical distribution system and verifies that equipment interrupting and withstand ratings are adequate for the calculated fault levels.
- Available fault current calculations
- Equipment duty evaluation
- Utility, generator, and motor contribution modeling
- Transformer, cable, and other system impedance modeling
Protective Device Coordination
Protective device coordination evaluates breakers, fuses, relays, and other protective devices to improve selective coordination and reduce unnecessary outages where practical.
- Time-current characteristic curve (TCC) development
- Breaker and relay settings evaluations
- Optimize balance between safety, protection, and coordination
- Minimize risk of nuisance tripping due to transformer/motor inrush or other transients
Arc Flash Hazard Analysis
Arc flash hazard analysis calculates incident energy, arc flash boundaries, and required labeling information to support electrical safety programs and energized work planning.
- IEEE 1584 incident energy and arc flash boundary calculations
- Application of current applicable NFPA 70E recommendations
- Energy reduction maintenance switch and arc flash mitigation evaluation options available
- NEC compliant arc flash labels
Two Decades of Industry Experience
Built from 20 years of experience in power systems analysis, Power System Calcs provides short circuit, coordination, and arc flash studies for facilities ranging from commercial and industrial sites to multi-building hyperscale data centers.
Rooted in the nuclear power industry and refined through mission-critical facility work, our process emphasizes model accuracy, quality assurance, personnel safety, and isolation of faults to the extent possible.
Our studies apply ANSI, IEEE, OSHA, and NFPA 70E guidance to ensure NEC compliance and to support clear hazard identification, appropriate selection, and defined safe working distances.
Through this experience, we have developed a unique, highly specialized workflow that supports the efficient execution of large, complex projects with demanding schedules while maintaining high quality deliverables and minimizing the risk of human error.
Accurate, efficient, and safety focused studies.
- 20 years of power systems analysis experience
- Studies for commercial, industrial, and hyperscale data center facilities
- Refined workflow focused on model accuracy and consistent results
- Evaluations guided by ANSI, IEEE, OSHA, and NFPA 70E requirements
