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




4

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

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.

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 on the outer end of the outgoing cables, where they connect into the main switch of the small shops DB

Review and Recommendations

• Refer to section 2 and 3 to assist in prioritising repairs which have been highlighted

by this thermographic survey.

Electrical Compliance and General Condition Report

• All issues of electrical non-compliance are detailed in section 4.

• Issues which have been highlighted, should be dealt with as promptly as possible.

Electrical Maintenance

• No evidence of recent testing and maintenance of ACB’s was noted at time of site

visit.

• A fault developing in an ACB would lead to a major loss of power

• A routine of scheduled maintenance would mitigate against this risk

• ACBs 1 and 2 were last serviced in 2015.
