The following is what we do when conducting a typical thermographic survey:

  • Visual and Mechanical Inspection
    1. Inspect for physical, electrical, and mechanical condition.
    2. Remove all necessary covers prior to thermographic inspection.

  • Equipment to be inspected shall include all current-carrying devices, provided it meets the criteria in "Test Parameters" stated in #3 (See Below).
    In our computer generated report the following will be provided:
    1. Abnormalities in operating equipment.
    2. Temperature difference between the area of concern and the reference area.
    3. Cause of temperature difference.
    4. Areas inspected. Identify inaccessible and/or unobservable areas and/or equipment.
    5. Identify load conditions at time of inspection.
    6. Visible light photographs, when practical and/or thermograms of the deficient area.*

  • Test Parameters
    1. Inspect distribution systems with imaging equipment capable of detecting a minimum temperature difference of one degree Celsius at 30 degrees Celsius.
    2. Equipment shall detect emitted radiation and convert detected radiation to visual signal.
    3. Thermographic surveys should be performed during periods of maximum possible loading but not less than forty percent (40%) of rated load of the electrical equipment being inspected. (NFPA 70B - 1990, paragraph 18-16.5)
      4.

  • Test Results
      Category 1. Temperature differences of 1 degree Celsius to 3 degrees Celsius indicate possible deficiency and warrant investigation only.
      Category 2. Temperature differences of 4 degrees Celsius to 15 degrees Celsius indicate deficiency; Repair at a planned date in the future.
      Category 3. Temperature differences of 16 degrees Celsius and above indicate major deficiency; Immediate repair required.
