Engineering for owners and operators who need a power system studied, a failure diagnosed and corrected, or a facility designed. The engineer has led or directed more than 400 forensic investigations of electrical failures and knows which details end up mattering.

Most electrical failures trace back to something that was knowable earlier: a protective device set outside the coordination study, a study built on a one-line that no longer matched the equipment, a maintenance interval that lapsed. An engineer who investigates those failures knows to look at the details that cause them.
Every engagement is handled personally by Jay Prigmore, Ph.D., P.E. The same engineer scopes the work, builds the model, and signs the deliverable.
IEEE 1584-2018 incident-energy analysis, arc flash labeling, and NFPA 70E program support, from a voting member of the IEEE 1584 working group. Independent review of an existing study is available as a separate scope. More on arc flash →
Short-circuit, load flow, motor starting, and protective device coordination for low-, medium-, and high-voltage systems, performed to IEEE 399 and IEEE 242 practice. Deliverables include the model, the settings recommendations, and the reasoning behind them, so the next engineer can check the work.
Partial discharge testing, transformer DGA interpretation to IEEE C57.104, and power quality investigation for industrial and data center assets, including the question owners most often need answered: whether a condition is getting worse. Transformer diagnostics → · Power quality →
Medium-voltage distribution, protection, and DC power design for data center, industrial, offshore, and renewable facilities, sealed in states where the P.E. license is active at the time of the work.
Root-cause investigation when a failure needs to be understood and prevented rather than litigated, drawing on five years leading electrical quality and field reliability engineering for a global hyperscale data center fleet. If the matter later becomes a claim, the evidence has already been handled correctly. Forensic investigation →
Modeling tools: EasyPower, ETAP, SKM PowerTools, ARCAD, PSCAD, PowerWorld, and MATLAB/Simulink, chosen to match the owner’s existing model where one exists. Design and relay software: AutoCAD and Revit for drawings and construction documents; AcSELerator and Easergy for relay settings.
Yes, in states where the Professional Engineer license is active at the time of the work. Jay Prigmore holds P.E. licensure in 18 states, and additional states are available via NCEES record. The licensure that applies to a project is confirmed in the written proposal.
Yes. Independent review of an existing arc flash, short-circuit, or coordination study is a common engagement: checking the model against the as-built one-line, the inputs against their sources, and the results against the governing standard. For a lower-cost automated first pass on an existing arc flash study, Ohmics is available as a separate product.
From the one-line and a short description of the facility and the question to be answered. A written proposal sets out the scope, the data needed, the deliverables, the schedule, and the fee before any work starts.
