Power System Analysis and Energy Audits
Modern electrical distribution systems are complex and addressing voltage drop, poor voltage regulation, low power factor, and high harmonic content requires our expertise.
We will collect data on your system, run system models on our computer software, and help you answer questions like:
- What is my current system capacity?
- Does my existing system have room for growth?
- What can I do to reduce my electrical utility bills?
- Why do we keep burning up expensive VFDs?
- We have severe light flickering problems. What can we do?
- We lose utility power frequently. Will a generator help?
- Should we install an uninterruptible power supply (UPS)?
- Why do we keep tripping circuit breakers or blowing fuses?
Power System modeling and analysis can answer the above questions and correct common problems related to voltage drop, poor voltage regulation, low power factor and high harmonic content.
Power Factor Correction can even help lower your electric utility bill.

Arc Flash Hazard Analysis
Strict Compliance With Industry Standards
The National Electrical Code (NEC) requires certain industrial electrical equipment to have arc flash warning labels.
NFPA 70E "Standard for Electrical Safety in the Workplace" and IEEE 1584 have guidelines for conducting hazard/risk assessments to determine arc flash levels at each panel in the distribution system.
Arc Flash Reduction Solutions
Thor Engineering, LLC has performed many successful arc flash hazard analyses and power distribution system studies at large Fortune 500 industrial facilities nationwide. Our goal is to get your arc flash levels as low as practically possible.
To achieve this goal, we use the latest technology and industry trends available at the time. We have successfully mitigated arc flash levels for many clients over the years. We can provide complete turnkey arc flash mitigation solutions.
How We Work
We come out to your site to collect field data needed for an arc flash hazard analysis. We then use computer modeling software (Easypower or SKM) to create a model of the power distribution system.
Our experts base our calculations on NFPA 70E and IEEE 1584 standards to identify incident energy levels (cal/cm2), flash boundaries, and personal protective equipment (PPE) ratings.
Our full range of services covers:
- Field Data Collection Services
- Short Circuit Analysis
- Verification of Equipment Interrupting Ratings
- Protective Device Coordination Analysis
- Calculation of Incident Energy Levels (Cal/cm2)
- Calculation of Arc Flash Boundaries
- Shock Hazard Analysis
- Personnel Protective Equipment
- Custom Printing of Warning Labels and Signs
- Installation of Warning Labels and Signs
- Onsite adjustment of circuit breaker & relay trip settings
- Comprehensive Full-Color Report With Recommendations
- On-Site Electrical Safety Training
- Electrical Safety Program Development

Electrical Safety and Compliance Services
We offer quick and thorough assistance to clients with OSHA citations for electrical safety violations, substantially reducing their fines. Our turnkey safety solutions comply with the industry standard:
NFPA 70E "Electrical Safety in the Workplace.”
We can develop your corporate or plant-level electrical safety program, standards of practice, and lock-out-tag-out procedures.
On-Site Electrical Safety Training
Our training program is called “A Practical Application of NFPA 70E”. Our training helps close the loop between the results of the Arc Flash Hazard Analysis and your Electrical Safety Program. We address hazards found specifically in your plant. Our training is geared towards the maintenance employee. Our class is taught by a senior electrical engineer with over 20 years of experience as a plant engineer and maintenance manager running an entire maintenance crew in a chemical plant.
Our typical class is 4 hours long and includes powerpoint presentation, videos, PPE demonstration, and real-world scenarios with Q&A. Our handouts include: training manual, pen, hardhat sticker, and wallet card.
