Even new equipment can arrive with problems. ACMT Infrared Services Ltd. offers infrared electrical inspections to Western Canada, including BC, Alberta, Saskatchewan, and Manitoba. This inspection should be scheduled following the initial start-up and shortly before the warranty expiration date. This scheduling can save the company thousands in equipment and potential production loss, which could have cost millions. The anomaly in the thermogram on this page was identified about 1 week before the warranty expiration date and saved the company thousands in internal repair costs, not to mention the potential production loss which could have entered the high six-digit area. While this anomaly is visible at the bushing, repairs were attempted at the visible bolted connections to eliminate all possibilities, only to find the anomaly increase in temperature. The source turned out to be an internal buss connection, likely loose right from the factory, which led to the identification of manufacture design problems.
Compare these 2 components and analyze the differences before coming to any rushed decisions. While the source of the energy observed on this insulator appears to come from the top connection, the temperature decreases along the top line through the insulator. This equipment was shut down as per the thermographers analysis to further investigate the internal components related to this insulator, only to find the bottom connection severely burned and only millimeters from burning completely through, potentially causing a catastrophic situation.
