Section 1, Preamble:
Report Guidelines This Report of Infrared Inspection provides complete documentation of thermal patterns
detected in your in your equipment, structure or system. It uses a subjective evaluation to
help you prioritize repairs to provide the greatest return from this inspection and your
maintenance.
The Report of Infrared Inspections meets the documentation requirements of the
Infraspection Institute Standard for Infrared Inspection of Electrical Systems and Rotating
Equipment, as well as standards, practices and specifications published by ASTM, NFPA
and NETA.
How Infrared Thermography Works Infrared Imagers “see” the heat radiated from your equipment in real time, just like a video
camera sees visible light. In colour thermograms, colours in the scene are matched to the
reference bar. Colours appearing closer to the top of the reference bar indicate higher
temperatures. Colours appearing closer to the bottom of the reference bar indicate lower
temperatures.
Repairs and Priority Ratings Each thermogram is given a Subjective Repair Priority Rating which is based upon your
qualified assistant’s opinion of how critical the subject item is to the safe and profitable
operation of your overall system. The Inspection Summary section of this report explains
how to use this Subjective Repair Priority Rating to help you determine how quickly you
need to investigate and correct the potential problem. Overheating can cause premature
deterioration and costly, unplanned failure of your equipment. Overheating connectors,
conductors and components will never get better. In fact, the temperature and rate of
deterioration will increase with time. No one can predict when a failure will occur. As a
result we suggest that you use the Subjective Repair Priority Ratings as a guide but that
you investigate and take the appropriate corrective measures as soon as possible.

A Hypothetical Fault Cycle of a “Hotspot”
The birth of a hot spot is shown at point “A”.
This hot spot can progress in many ways:
1) It can fail in a matter of hours after birth;
2) It can follow the simulated pattern as shown in the graph and fail at any point or go
indefinitely.
The only thing to keep in mind is that it will never cure itself. It will eventually FAIL.
Temperature Versus Deterioration
An investigation of hundreds of contactors has shown that many with small temperature
rises (5 to 10ºC) above ambient were seriously deteriorated and others with temperatures
of 100ºC or more had very little deterioration and vice versa.
The reason for this paradox is that excessive heating over an extended period causes
connections to arc and burn to the point where severe deterioration takes place. Arcing
causes the connector to weld to the conductor which forms a low resistance path for

current flow. As a result, heating of the components drops and may even cease entirely for
a time. These unintentional welds are generally poor ones and are easily broken by
mechanical stress, high load or fault currents. Once such a weld separates, heating and
arcing takes place again until the connector re-welds to the conductor. Meanwhile,
disintegration continues and, if not detected by inspection, the equipment eventually fails.
Conclusion : Don’t be misled by temperature. Temperature does not necessarily
indicate the severity of a fault. Consider the importance of each faulty component
within the framework of your whole system. Which faults, when they fail, will cause
you the greatest interruption.
Qualitative Report
Please note, that unless otherwise stated this is a qualitative report. That is, we are only
concerned with the thermal patterns that have been observed, and not the actual
reported temperature. With an emissivity value to set 1.0 in the thermal imagers
computer, the temperature values serve only as a reference and do not provide an
accurate measurement of temperature. Temperature values stated are apparent
temperatures only, and as such are understated values. This means that in most cases the
temperature values will be the most conservative value and that actual temperatures may
be significantly greater.
Inspection Summary For the equipment inspected, we have recorded thermogram(s) and/or photographs to
document conditions found during our inspection. These thermograms and/or photographs
appear on the Image Pages found in section 3 of this report.
As a reference, each Image Page contains Evaluation Priority Ratings. Subjective
Evaluation Ratings are based upon the Qualified Thermographer’s opinion of the subject
item’s importance to the safe and continuous operation of the facility.

Section 2, Image summary:
Glossary of Terms:
OK - No observable thermal exception. The result of “OK” indicates that no heat anomaly was found at the time of inspection. This does not guarantee that no fault is present. Circuits are required to be under load for testing to provide adequate results. While all reasonable care and effort was taken to ensure load was optimal at the time of inspection, it is not possible to have all circuits under load at the time of testing. NA – No Access. No Access could be due to site safety concerns, hazards, locks, obstacles/obstructions, or protective coverings preventing line of sight access to the components. Recommend fitting of IR transmissive windows. OFF – Circuit not in use or not running. General Fault – No thermal anomaly at time of survey, however other safety/OHS/non-compliance issue noted. Refer to section 4, for images and further details

Thermal signature supports current measurements indicating an unbalance three phase circuit. The electrical installation should be balanced as far as practicable in line with standard AS/NZS 3000: 2018 Appendix C. White Phase is also running close to circuit limit increasing chance of blowing fuse or damaging cable.

High heat signature on the Red phase may indicate the circuit is out of balance. The electrical installation should be balanced as far as practicable in line with standard AS/NZS 3000: 2018 Appendix C.
Repair suggestions
Further safe investigation into the current loads for the three phases in this circuit is warranted. This could be achieved by installing data loggers onto the other end of outgoing cables. IE: where they connect into the main switch of DB3.
