NETA Thermographic Infrared Survey Report

It covers the full workflow for an infrared scan of energized electrical equipment: survey conditions, asset identification, thermal and visible-light evidence, delta-T classification, corrective priority, and signoff. The template is built to capture the details an inspector needs to support a finding and hand it off for repair. It is not a maintenance work order or a general electrical inspection checklist.

Use it when you are performing a planned thermographic survey on switchgear, panelboards, MCCs, disconnects, transformers, or other accessible electrical assets. It is especially useful when equipment must remain energized and the scan is being done under established electrical safety controls. Do not use it for de-energized acceptance testing or for non-thermal inspections that do not produce infrared evidence.

A qualified thermographer, electrical inspector, or maintenance professional trained to interpret infrared findings should complete it. The template includes fields for inspector qualification and supervisor review so the record shows who performed the scan and who accepted the closeout. If your site requires a licensed electrician or a specific credential, you can add that requirement to the form.

The cadence depends on your risk profile, equipment criticality, and internal maintenance program. Many organizations schedule scans on a recurring basis for high-load or mission-critical assets, and after abnormal events such as overheating, nuisance trips, or recent repairs. The template supports repeatable surveys, so you can compare findings over time and track recurring defects.

The template is structured to support NETA thermographic survey practices and to document the conditions needed for a defensible energized inspection. It also helps show that the scan was performed under electrical safety controls consistent with OSHA general industry expectations and site lockout-tagout or energized work procedures where applicable. You can add your facility's specific safety approvals, permits, or PPE requirements.

Common mistakes include missing the load condition at the time of scan, failing to capture both thermal and visible-light images, and recording a finding without identifying the asset or scan point. Another frequent issue is using vague language like 'hot spot' without a measured temperature, reference temperature, or delta-T classification. The template helps prevent those gaps by prompting for the evidence and context that make the finding actionable.

Yes. Sites often tailor delta-T bands, priority labels, and target completion windows to match their internal risk matrix, equipment criticality, and maintenance response times. If your program follows a specific NETA-based severity scheme or internal classification standard, you can replace the default labels with your own. The report structure still works as long as each finding has a measurable basis and a clear action.

The corrective priorities section includes a work order or ticket number field so findings can be linked directly to your CMMS, EAM, or ticketing system. That makes it easier to track ownership, due dates, and closure evidence without retyping the defect description. You can also add asset IDs or location codes that match your maintenance system to reduce duplicate entry.

Use the corrective priority and immediate risk fields to flag the issue for urgent review, then follow your site's electrical safety and outage escalation process. The report should document the observed condition, the likely cause, and the recommended action, but it should not replace a formal hazard response or switching procedure. If the issue suggests imminent failure, route it to the responsible supervisor and maintenance team right away.
