Inside an Infrared Survey: Industrial Facility Report
This is an anonymized sample of a real Invizions infrared inspection report for an industrial manufacturing plant. It shows how we scan an entire facility's electrical and mechanical systems, trend results year over year, and document each thermal exception with an objective NETA priority rating and a clear corrective action.

Report Foreword
Every Invizions report provides complete documentation of the exceptions — abnormally warm or cool equipment — found during the infrared inspection of your equipment. It uses a variety of data and ratings to help prioritize your repairs and give you the greatest return from your maintenance efforts.
Inspections are performed and prepared by a Certified Infrared Thermographer. To earn this certification, the thermographer must complete coursework and pass examinations administered by the Infraspection Institute.
This report fully meets the requirements of the Infraspection Institute's “Guidelines for Infrared Inspection of Electrical and Mechanical Systems.” It also references, incorporates, and exceeds all other published guidelines and standards pertaining to the infrared inspection of electrical and mechanical systems, and is conducted to NETA (National Electrical Testing Association) standards.
Year-Over-Year Trending
This facility is on a recurring annual inspection program. Each asset carries a status history, so developing problems can be spotted as they emerge and verified as repaired. Every one of the 60 monitored assets is logged with a status for each visit — OK (no problem found), EX (exception/potential problem), N/O (not operating), or OFF — building a maintenance record that gets more valuable every year.

How Findings Are Prioritized
Temperature Severity Ratings are objective and based on temperatures measured by the thermographer. The exception temperature is compared against a reference temperature on a similar healthy component (or against ambient air for operating equipment) to produce a delta-T — the temperature rise — which maps to the NETA Priority Criteria for Electrical & Mechanical Exceptions:
10–18°F rise
Possible deficiency; warrants investigation.
218–36°F rise
Probable deficiency; repair as time permits.
336–72°F rise
Monitor continuously until corrective measures can be accomplished.
472°F & above rise
Major discrepancy; repair immediately.
Inspection Summary
Over a one-day survey, the thermographer scanned switchgear, distribution panels, disconnects, motor control centers, transformers, and operating motors across 60 assets spanning the basement through the fourth floor. Most tested normal (“OK”); six thermal exceptions were identified and documented for corrective action.
