Internal switchgear components and associated wiring were inspected for abnormal operating temperatures effected 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 switchboards and associated wiring within were thermally operating within load conditions. Internal wiring insulation and terminations appear to be sound with exceptions as listed within. 1

2 General Information Application Thermal Scanning 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. 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 20 C and 40 C 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. 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 Recommended Action 0 No Fault. Re-scan within 12 months 1 Disconnect supply immediately 2 Arrange service /repair within 24 hours 3 Arrange service/repair at very next service opportunity 4 Arrange service/repair at next scheduled maintenance 5 Condition monitor Licensed electricians must perform all repairs and service.
