An Infrared Thermal Scan of Listed Electrical Switchboards was conducted XXXXXX. The complex was drawing load from the Local Supply Authority at time of inspection. Internal switchgear components and associated wiring were inspected for abnormal operating temperatures affected by load or equipment condition. Wiring and terminations were inspected for high resistance connections and insulation condition. Load conditions were as experienced during periods of normal demand. All inspected online switchboard components and associated wiring were thermally operating XXXXXXXXXXXXXXXXXX. Internal wiring insulation and terminations appear to be XXXXXXXXXXXXXXX.

REPORT SUMMARY

- 4 -

The information listed below is to assist in the interpretation and discharge of appropriate remedial action of reported faults or potential areas of concern. Recommendations listed within this report are within the area of our expertise and recommend you discuss the implementation of service/repair with your maintenance service provider. Scope Infrared Thermal scan of electrical switchgear and associated conductors to detect the evidence of equipment operating near or above rated thermal temperatures. Where possible load readings are taken to ensure proper diagnosis of prospective faults. Australian and IEC Standards along with Copper & Brass Association publication No.22 are used as benchmarks for assessing permissible temperature limits. Australian Standards state that in all switchboards the temperature rises (on the outer panels) shall be referred to ambient. Referring to accessible boards – i.e. touchable, the rise is not to exceed 30° C, non-accessible boards 40° C. (extract from AS3439.1 ‘Low voltage switchgear and controlgear assemblies’ Table 3 Temperature limits). Where higher temperatures are applied to components, the insulation maximum should not be exceeded Maximum temperatures (These are not recommended operating temperatures)

Bare Copper & Aluminium - 75° C MIMS cables – up to - 90° C PVC insulation V-75 cables - 75° C Silver/Nickel Coated cables - 105° C Actual Tin Coated cables - 90° C High temperature cables - 105° C Electrical Equipment - 50° C (to maintain maximum current and fault ratings) Connections – as above + 15° C

Method All accessible covers are removed from the switchboards with internal PVC shrouds removed when installed in a manner that facilitates safe removal. Switchboards assigned a segregation rating greater than two (2), in accordance with AS3439, or where fitted with internal busbar shrouds can be arranged to be scanned with the arrangement of at least two shutdowns to remove and reinstall covers. Internal metal covers will not be removed whilst the switchboard is on line.

An infrared radiometer with its range initially set at 20C to 40C is passed over all switchgear, bus system and cable connections. Areas displaying abnormal temperature variations are further investigated by means of equipment application analysis, load measurement and pinpoint temperature readings. Faults and areas of concern have infrared thermal and digital images saved for report and condition monitoring tasks. Thermal detection and analysis via infrared radiation is limited by the amount of current passing through the system. Equipment should be loaded to enable it to generate an appropriate amount of heat to detect an abnormality. The amount of current required to detect or analyse an abnormal thermal condition varies from system to system and is dependent on its current carrying capacity, ambient temperature and inherent design.

Results A priority rating schedule along with suggested remedial action plans are included for prioritising rectification works. Where faults of a life or property threatening situation are detected, notification will be immediately made to the client’s representative. Ultimately it is the owner or plant operator’s responsibility to implement or gain further advice of the recommended repairs contained within this report. Each thermal image is uniquely identified to correspond with a label placed upon the affected equipment for ready identification by maintenance personnel.

Priority Rating Temp Rise ΔT⁰C Recommended Action

1 >40⁰C Corrective Action required immediately

2 >20⁰C - 40⁰C Corrective Action required as soon as possible

3 >10⁰C - 20⁰C Corrective Action required at scheduled maintenance

4 1⁰C - 10⁰C Condition monitor. Possible fault developing.

- - No Fault. Re-scan within 12 months

Licensed electricians must perform all repairs and service.
