Arc Flash Studies

Know the electrical hazards in your facility, and label and protect equipment accordingly

What it is

Arc Flash Studies

A power systems study models your electrical distribution system from the utility service down to the panelboards. We calculate available short-circuit current and incident energy, check that protective devices are rated and set correctly, and prepare equipment labels and a clear set of recommendations that facilities and safety teams can act on.

Typical duration: 3 to 8 weeks depending on the size and complexity of the system

The business problem

Why clients need this

Electrical systems change over time as loads are added, equipment is replaced, and utility conditions shift. Studies that were done years ago, or never done at all, leave workers exposed and equipment at risk.

01
Arc flash labels and one-line diagrams are missing, out of date, or no longer match the installed equipment.
02
Breakers and fuses may be undersized for the available fault current, or set so they do not clear faults quickly enough.
03
Electrical safety programs need current study data to support work procedures and personal protective equipment selection.

Our approach

How we deliver it

1
Data Collection & One-Line Diagram
Field verification of equipment nameplates, cable sizes, transformer data, and protective device settings, used to build or update the single-line diagram.
2
System Modelling
Building a model of the system in power analysis software using utility fault data and verified equipment information.
3
Short-Circuit, Coordination & Arc Flash Analysis
Calculating fault currents, checking equipment ratings, reviewing device coordination, and calculating incident energy using IEEE 1584 methods.
4
Labels, Report & Recommendations
Arc flash labels, a written study report, and a prioritised list of setting changes and equipment upgrades.

Data & AI

How technology strengthens this service

The verified model is kept as a living digital record, so a change such as a new transformer or a utility upgrade can be re-run quickly rather than requiring a new study from scratch.

FAQs

Common questions

How often should an arc flash study be updated?+

NFPA 70E calls for reviewing the study at intervals not exceeding five years, and sooner after major changes to the system. Your safety program and authority having jurisdiction may set stricter requirements.

Do we need to shut down the plant for the data collection?+

Usually not. Much of the data can be collected with equipment energized, following your site's safe work rules. Some access may need to be scheduled around outages.

Will you tell us how to reduce incident energy levels?+

Yes. Where results are high, we identify options such as setting changes, maintenance modes, or equipment upgrades, and explain the trade-offs.
