Electrical Reliability Engineering for Critical Facilities.
Arc flash studies, preventive maintenance, infrared diagnostics, and compliance documentation for industrial operations that cannot afford uncertainty.

Technical capability
Build certainty into the electrical systems your operation depends on.
T.E.S.T.T. is built for facility leaders who need more than a contractor visit. We document equipment condition, identify failure risk, and give your team a defensible path from finding to corrective action.

The problem is rarely where it first shows up.
We do not stop at the symptom. We follow the signals through the system until the next action is clear.

Preventive Maintenance
Clean, inspect, tighten, torque, lubricate, and exercise critical gear against a documented maintenance standard.
CITTLE · NFPA 70B · RecordsInfrared Diagnostics
Identify abnormal thermal patterns and schedule corrective work before a loose connection becomes a shutdown.
FLIR · Exception reports · TrendingElectrical Systems Testing
Verify insulation resistance, breakers, controls, and equipment performance beyond what a visual inspection can prove.
Testing · Diagnostics · ReportingCompliance Programs
Close the gaps between your equipment condition, maintenance records, safety program, and audit obligations.
NFPA 70E · OSHA · NECSafety Training
Train qualified workers around the actual equipment, boundaries, PPE, and procedures inside their facility.

Peak temperature187°F
Field finding / Twin Cities Metro
A routine FLIR scan prevented a six-figure shutdown.
A food manufacturing facility had no visible damage, no burnt odor, and no tripped breakers. The infrared scan told a different story.
Situation
Routine annual scan of the main distribution panel.
Finding
A breaker termination measured more than 80°F above comparable circuits.
Outcome
Repair happened during planned downtime. No unplanned outage or worker exposure.
Engineering evidence package
What your team leaves with is built to operate, insure, and audit the facility.
Every engagement produces a practical chain of evidence. The finding is clear, the corrective route is documented, and the record is ready for the people responsible for the system after our team leaves.

Maintenance & Safety Record
Equipment condition, completed work, deficiencies, and the documentation trail needed for future trending.
PM record · Deficiencies · Compliance supportClient information stays protected. Facility names, proprietary values, and sensitive details are handled with the same discipline as the systems we document.
Field evidence
Real facilities. Real findings. No stock-photo theater.
Every image comes from actual T.E.S.T.T. work across Minnesota facilities.
Field verification
Measure at the equipment. Document what the system is actually doing.
Direct field measurements give facility teams a clearer record of equipment condition and a practical route from finding to corrective action.

Specialized electrical safety, backed by Minnesota electrical expertise.
T.E.S.T.T. combines systems analysis, preventive maintenance, diagnostic testing, and safety training into one coordinated reliability practice. The objective is simple: give the people responsible for the facility a clear record of what matters and what to do next.
